MAP OF OREGON SHOWING PRINCIPAL RIVERS. 



SURFACE WATER SUPPLY OF OREGON. 



By F. F. Henshaw and H. J. Dean. 



INTRODUCTION. 

The collection of hydrometric data was begun by the United States 
Geological Survey in 1888, when the United States Irrigation Survey 
was organized and a few gaging stations were established in various 
sections of the arid West. In 1890, stations were established in 
Oregon on Owyhee River at Owyhee and on Malheur River at Vale, 
and many discharge measurements were made. 

The Irrigation Survey came to an end in July, 1891, through lack 
of appropriations, but records were obtained at several stations in 
various parts of the United States, including those on Owyhee and 
Malheur rivers part of the time until 1895, and the division of hydrog- 
raphy continued in existence as a part of the topographic branch 
of the Survey. 

Since the fiscal year ending June 30, 1895, successive simdry civil 
biUs passed by Congress have carried appropriations for '' gaging the 
streams and determining the water supply of the United States 
* * * and for the preparation of reports upon the best methods 
of utilizing the water resources." 

The only records of stream discharge obtained in Oregon between 
1895 and 1903 were relating to Owyhee and Malheur rivers, 1895 to 
1897; UmatiUa River at Gibbon, where a station was established in 
1896; and Deschutes River at Moro and Hood River at Tucker's 
bridge, 1897 to 1899. Between 1894 and 1902 discharge measure- 
ments were made either by engineers sent out from the Washington 
office of the Survey, or by Sydney Arnold, resident hydrographer for 
the State of Washington, who made occasional trips into Oregon, 

The reclamation act was passed in 1902, and as a result the Recla- 
mation Service was organized as a branch of the Geological Survey. 
In 1903 John T. Whistler was appointed district engineer for Oregon, 
in charge of both stream measurements and investigations under the 
provisions of the reclamation act. 

Between 1903 and 1905 many gaging stations were established, 

chiefly in connection with investigations of possible irrigation projects. 

In 1905 the Oregon Legislature passed an act providing for an 

annual appropriation of $2,500 for the investigation of the water

resources of the State, and a like amount for topographic mapping, 
contingent on the allotment of an equal amount by the Geological 
Survey. At the same time the office of State engineer was created and 
John H. Lewis, formerly of the Geological Survey, was appointed by 
Governor Chamberlain. 

With the additional funds thus made available gaging stations were 
established on previously unmeasured streams rising in the Cascade 
Mountains. This new work was carried out under the direction of 
the State engineer, who was designated to represent the Geological 
Survey, as well as the State. 

In the spring of 1906 J. C. Stevens was pla?ie3 in charge of all 
hydrometric mvestigations in Oregon under the direction of D. C. 
Henry, supervising engineer. In July of that year the Reclamation 
Service was made a separate bureau and thereafter the work was 
carried on entirely by J. C. Stevens. In 1910 Mr. Stevens resigned 
and was succeeded by F. F. Henshaw. 

In 1911 the Oregon Legislature appropriated $20,000 annually for 
hydrographic and topographic work in cooperation with the United 
States Geological Survey, in addition to the $5,000 annually previ- 
ously appropriated, and of this $7,000 has each year been spent for 
stream measurements. None of the results obtained from the 
expenditure of these additional funds appear in the present report. 

In 1913 the State engmeer and the Director of the United States Geo- 
logical Survey entered into a contract by the terms of which there were 
to be contributed from the State survey fund, derived from a license tax 
on water powers, the sum of $3,000, the Geological Survey to contribute 
as its share an equal sum for compiling and printing stream-flow data. 
In 1914 a similar contract was executed, covering $3,000 derived from 
the license tax for the current year. In compliance with these agree- 
ments the present report has been prepared. The report embraces hy- 
drometric data from 1878 to September 30, 1910. The results of meas- 
urements for the years ending September 30, 1911 and 1912, have 
been published m Water-Supply Papers 310, 311, 312, 330, 331, and 
332. All the data here assembled have been carefully studied and 
the results have been recomputed when necessary to msure their best 
possible interpretation. For example, the daily discharge for a 
station may be computed the first year from a poorly defined ratmg 
curve; the next year, with additional measurements, a somewhat 
different curve may fit aU the points better without indicating that 
any change in channel has occurred. The second curve is therefore 
more truly apphcable to the gage readings of the first year than the 
one actually used, but in past reports covering only a given year no 
systematic effort has been made to revise the records of earlier years. 
No changes in previously published data, however, have been made 
uidcss apparently warranted by the accuracy of the field data. 



DEFINITION OF TERMS. 3 

COOPERATION. 

Many records have been collected and furnished to the United 
States Geological Survey by other Government bureaus and by private 
corporations and individuals. Such cooperation is duly acknowl- 
edged in the description of the stations. Special aclaiowledgment is 
due to the United States Weather Bureau and the United States 
Engineer Corps, whose stations on Columbia River at The Dalles 
and Cascade Locks and on Willamette River at Albany have made 
available records considerably longer than any kept by the Geological 

Survey alone. 

DIVISION OF WORK. 

The data for this report were compiled in the Portland office of the 
water-resources branch of the United States Geological Survey by 
H. J. Dean. Rating-curve studies and comparisons of data were 
made by F. F. Henshaw, district engineer, and H. J. Dean. The 
computations were made by H. J. Dean, C. L. Batchelder, and P. V. 
Hodges. The report has been edited by Mrs. B. D. Wood. 

DEFINITION OF TERMS. 

The volume of water flowing in a stream — the ^'run-off" or 'Mis- 
charge" — is expressed in various terms, each of which has become 
associated with a certain class of work. These terms may be divided 
into two groups — (1) those that represent a rate of flow, as second- 
feet, gallons per minute, miner's inches, and discharge in second-feet 
per square mile, and (2) those that represent the actual quantity of 
water, as run-off in depth in inches, acre-feet, and millions of cubic 
feet. The principal terms used in this report are second-feet, second- 
feet per square mile, run-off in inches, and acre-feet. They may 
be defined as follows: 

''Second-feet" is an abbreviation for "cubic feet per second." A 
second-foot is the rate of discharge of water flowing in a channel of rec- 
tangular cross-section, 1 foot wide and 1 foot deep, at an average 
velocity of 1 foot per second. It is generally used as a fundamental 
unit from which others are computed by the use of the factors given 
in the tables of convenient equivalents (pp. 4-6). 

"Second-feet per square mile" is the average number of cubic feet 
of water flowing per second from each square mile of area drained, 
on the assumption that the run-off is distributed uniformly both as 
regards time and area. 

"Run-off, depth in inches," is the depth to which the drainage area 
would be covered if all the water flowing from it in a given period were 
conserved and uniformly distributed on the surface. It is used for 
comparing run-off with rainfall, which is usuaUy expressed in depth 
in inches. 



4 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

All "acre-foot" is equivalent to 43,560 cubic feet and is the 
quantity required to cover an acre to the depth of 1 foot. The term 
is commonly used in connection with storage for irrigation work. 

The following tenns used in this report are not in very common use: 

''Discharge relation" is an abbreviation for the term ''relation of 
gage height to discharge." 

"Control," "controlling section," and "point of control" are terms 
used to designate that section or sections of the stream below the gage 
which determine the discharge relation at the gage. It should be 
noted that the control may not be the same section or sections at all 
stages. 

The "point of zero flov/" for a given gaging station is that pomt 
on the gage — the gage height — to which the surface of the river 
would fall if there were no flow.

EXPLANATION OF DATA. 

The data presented in this report, in general, are divided into the 
years beginning October 1 and ending September 30 of the following 
year. At the 1st of January in most parts of the country a large 
amount of the precipitation for the preceding three months is stored, 
either as ground water, in the form of snow, or in lakes. This stored 
water passes off in the streams during the spring break-up. At the 
end of September the only stored water available for run-off in the 
streams is possibly a small amount held in ground storage. There- 
fore the run-off for a year, beginning with October 1, is practically all 
derived from precipitation occurring within that year. 

For each regular current-meter gaging station the following data 
are given: Description of the station, list of discharge measurements, 
table of daily gate height, table of daily discharge, table of monthly 
and yearly discharge and run-off. 

In addition to statements regarding the location and installation 
of current-meter stations, the descriptions give information in regard 
to any conditions that may affect the constancy of the discharge 
relation, covering such points as ice, logging, shifting channels, and 
backwater; also information regarding diversions which decrease the 
total flow at the measuring section. Statements are also made regard- 
ing the accuracy of the data. 

The table of daily gage height shows the daily fluctuations of the 
surface of the river as found from the mean of the gage readings taken 
each day, usually in the morning and in the evening, though at many 
stations only one reading is made each day. At a comparatively few 
stations automatic gages are used, some of which give a continuous 
record of river stage in the form of a hydrograph and others a record 
printed at regular intervals, from which the mean daily gage height can 
be computed. The gage height given in the table represents the eleva- 
tion of the surface of the water above the zero of the gage. All gage 
heights affected by the presence of ice in the streams or by backwater 
from obstructions are published as recorded, with suitable footnotes. 
The rating table is not applicable for such periods unless the proper 
corrections to the gage heights are known and applied . Attention is 
called to the fact that the zero of the gage is placed at an arbitrary 



ACCURACY OF FIELD DATA AND COMPUTED RESULTS. 7 

datum and has no relation to zero flow or the bottom of the river. In 
general the zero is located somewhat below the lowest laiown surface 
elevation, to avoid negative readings. 

The discharge measurements and gage heights are the base data 
from which rating tables, daily discharge tables, and monthly dis- 
charge tables are computed. 

The rating table gives, either directly or by interpolation, the dis- 
charge in second-feet corresponding to every stage of the river re- 
corded during the period for which it is applicable. It is not pub- 
lished in this report, but can be determined from the tables of daily 
gage height and daily discharge. 

The table of daily discharge determined from the rating table gives 
the discharge in second-feet corresponding to the mean of the gage 
readings observed each day. 

The base data for the tables of monthly discharge presented in this 
report, unless otherwise stated in description of station, have been 
collected by the methods commonly used at current-meter gaging 
stations and described in standard textbooks. 

In the table of monthly discharge the column headed "Maximum" 
gives the mean flow, as determined from the rating table, for the day 
when the mean gage height was highest. As the gage height is the 
mean for the day, it does not indicate correctly the stage when the 
water surface was at crest height, and the corresponding discharge was 
consequently larger than given in the maximum column. Likewise, 
in the column of "Minimum" the quantity given is the mean flow for 
the day when the mean gage height was lowest. The column headed 
"Mean" is the average flow in cubic feet for each second during the 
month. On this the computations for the remaining columns, which 
are defined on pages 3 and 4, are based. 

ACCURACY OF FIELD DATA AND COMPUTED RESULTS. 

The accuracy of stream-flow data depends (1) on permanence of the 
discharge relation, and (2) on the accuracy of observation of stage, 
measurements of discharge, and interpretation of data. 

In order to give engineers and others information regarding the 
probable accuracy of the computed results, footnotes are added to 
the daily-discharge tables, stating the probable accuracy of the rating 
curves used, and an accuracy column is inserted in the monthly- 
discharge table. For the rating curves ^'weU defined" indicates, in 
general, that the rating is probably accurate within 5 per cent; 
'^fairly well defined," within 10 per cent; "poorly defined" or 
''approximate" within 15 to 25 per cent. These notes are vcr}^ 
general and are based on the plotting of the individual measurements 
with reference to the mean rating curve. 



8 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

The accuracy column in the monthly-discharge table docs not 
apply to the estimate of maximum or minimum discharge nor to 
that f(^r any one day, but to the monthly ]nean. It is based on the 
accuracy of the rating curve, the probable reliability of the observer, 
the number of gage readings per day, the range of the fluctuation in 
stage, and knowledge of local conditions. In this column, A indicates 
that the mean monthly flow is probably accurate within 5 per cent; 
B, within 10 per cent; C, within 15 per cent; D, within 25 per cent. 
Special conditions are covered by footnotes. 

Even though the montlily means for any station may represent 
with a high degree of accuracy the quantity of water flowing past 
the gage, the figures showing discharge per square mile and depth of 
run-off in inches may be subject to gross errors which result from 
including in the measured drainage area large noncontributing dis- 
tricts or omitting estimates of water diverted for irrigation or other 
use. On this account the computations of ^'second-feet per square 
mile" and '' run-off, depth in inches" have not been made for streams 
draining areas in which the annual rainfall is less than 20 inches, nor 
for those stations draining areas in which the precipitation exceeds 
20 inches of rainfall if such computations might be uncertain or mis- 
leading because of the presence of large noncontributing districts in the 
measured drainage area, because of the omission of estimates of water 
diverted for irrigation or other use, or because of artificial control or 
unusual natural control of the flow of the river above the gaging station. 
For example, estimates of run-off per square mile are not given for 
streams east of the Cascades, practically all of which are affected by 
diversions, are spring fed, or drain areas wholly or partly arid, nor for 
the many spring-fed streams on the west side of the Cascades. The 
stations in Oregon for which estimates of run-off per square mile are 
given and the drainage area used in the computation are listed as

NATURAL FEATURES OF OREGON. 9 

All figures of ''second-feet pel square mile" and "run-off, depth 
in inches" previously published by the Survey should be used with 
extreme caution, and such figures in this report should be used with 
care because of possible inherent sources of error not known to the 
Survey. 

In general the base data collected each year by the Survey engineers 
are published not only to comply with the law but also to afford 
any engineer the means of analyzing in detail the results of the com- 
putations. The table of monthly discharge is so arranged as to give 
only a general idea of the flow at the station and should not be used for 
other than preliminary estimates. The determinations of daily dis- 
charge allow more detailed studies of the variation in flow. It 
should be borne in mind that the observations in each succeediag 
year may be expected to throw new light on data already collected 
and published. 

NATURAL, FEATURES OF OREGON.^ 
TOPOGRAPHY. 

A line of mountains — the Cascade Range — extending north and 
south across the State divides Oregon into a western humid region 
and an eastern arid region. The range merges into the Klamath 
Mountains on the south and extends northward, broken only by the 
narrow pass of Columbia River at Cascade Locks, across the State of 
Washington into British Columbia. Its general elevation in Oregon 
is less than 6,000 feet above sea level, though isolated peaks exceed 
10,000 feet in altitude. Mount Hood, a volcanic peak near the 
northern extremity of the range in Oregon, is the highest mountain 
in the State and reaches an elevation of 11,225 feet.^ The range is 
of volcanic origin, and its slopes, especially on the west, are deeply 
eroded. Numerous streams, many of them excellent for power 
development, rise on its western slopes and most of them join Willa- 
mette, Umpqua, or Rogue rivers. The eastern slopes give rise to 
few streams. Deschutes River, parallel to the range and discharging 
into the Columbia above Celilo, is the largest. 

Between the Cascade Range and the Pacific Ocean is the Coast 
Range. This range was formed by uplift and distortion of the coastal 
plain and has been deeply dissected by erosion. It receives copious 
rainfall, and its valleys are traversed by many short but torrential 
streams. 

South of the Coast and Cascade ranges and merging into them is 
the Siskiyou Ridge of the Klamath Mountams, which has also been 
deeply dissected by erosion. The most important valle^^s in this

10 SURFACE WATER SUPPLY OF OREGON, 18*78-1910. 

ridgo are occupied by Rogue, Coquille, and Illinois rivers. In the 
northeastern part of the State are the Blue Mountains and the Wal- 
lowa Mountains, in wliich the general elevation is 8,000 feet and 
isolated peaks rise to greater height. The most important streams 
flo^vulg from these mountains are Umatilla, Grande Ronde, Powder, 
and Silvies rivers. Many of the valleys are comparatively smooth, 
but because of the great dissection to which the mountams have 
been subjected the topography is commonly rough and broken. 

The central and southern parts of the State consist of a high arid 
plateau over which arc scattered many volcanic craters and which is 
so broken by cliffs and valleys that its appearance is in many places 
mountainous. Many of the valleys in this region contain large shallow 
lakes, some of which are permanent and others merely playas. 

The topography of the region thus includes types ranging from 
the chaotically wild gorges of the Snake River basin to the level sage- 
brush plains of the Umatilla or the rolling prairies of Willamette 
VaUey. Dense forests clothe the region west of the Cascades and 
are scattered over the better watered highlands of the interior, but 
the arid plains are generally treeless. 

A large proportion of the total area of the State is covered by the 
vast lava flow which stretches from Mount Shasta north into British 
Columbia and from the Willamette VaUey east to the upper reaches 
of Snake River. Its successive flows cover the country with a 
mantle of great thickness. It is overlain with a thick covering of 
volcanic ash which forms the soil over a large portion ^of the State. 
Over large areas in central Oregon this soil is pumiceous ; it is so loose 
and porous that most of the moisture reaching it passes directly into 
the ground and finds its way into the underlying lava rock, going 
finally to feed the copious springs which issue from the rocks. This 
occurrence of pumice overlying lava is the chief cause of the remark- 
able steadiness of flow of Deschutes and Klamath rivers and their 
tributaries. 

CLIMATE.! 

Mean temperature in Oregon differs with elevation and with dis- 
tance inland. In Columbia River valley and west of the Cascades 
at points below 2,000 feet above sea level it is approximately 52° F.; 
east of the Cascade Range and south of the Columbia it ranges from 
43° to 51°. A universal characteristic is the uniformly low tempera- 
ture of the summer nights. In the coastal strip the greatest annual 
range in temperature is from 10° to 97°, with an average of 217 
days between frosts. In the valley strip between the Coast and 
Cascade ranges the range is greater; maximum recorded tempera- 
tures for Portland and Ashland have been 102° and 108° F., respec-

lively; minimum temperatures for those places have been —2° and 
— 4° F. The average time between last and first frosts ranges from 
213 days at Portland to 179 days at Ashland. In the higher sections 
of this district the extremes of temperature both daily and yearly are 
more marked, and at Lakeview, elevation 5,060 feet above sea level, 
frosts have occurred every month in the year. The higher elevations 
of the Cascades and the Blue Mountains are subject to lower tem- 
peratures than those mentioned. 

Rainfall ranges from less than 8 inches in the southeastern part of 
the State to more than 138 inches in the northwestern coastal strip, 
and averages from 75 to 138 inches along the coast, from 20 to 45 
inches in the valley region west of the Cascade Range, from 50 to 100 
inches in the Cascades, from 8 to 22 inches on the central high plateau, 
from 10 to 15 inches in the Columbia VaUey east of the Cascades, and 
from 12 to 25 inches in the f oothiUs and valleys of the Blue Mountains. 
Maximum precipitation occurs in winter, and summers are dry. 
East of the Cascades there is a secondary maximum precipitation in 
May and June. 

HYDROGRAPHY. 
RIVERS. 

The principal rivers of Oregon discharge into the Pacific, either 
indirectly through the Columbia, as do Malheur, Owyhee, Powder, 
Grande Ronde, Umatilla, John Day, Deschutes, and Willamette 
rivers, or directly, as do Siletz, Umpqua, CoquiUe, Rogue, and 
Klamath rivers. (See PL I.) 

Most of the streams of central, south-central, and southeastern 
Oregon, however, discharge into the land-locked lakes of the Great 
Basin. Few of the rivers of this region are perennial, and the large 
shallow lakes that occupy the chief depressions are permanent only 
when evaporation is balanced or exceeded by inflow. Where surface 
flow is deficient intermittent lakes or playas are formed. The chief 
streams of the Great Basin region are Chewaucan, Ana, Donner und 
Blitzen, and Silvies rivers; the important lakes are Warner, Harney, 
Malheur, Abert, Summer, and Silver lakes. 

Goose Lake, in south-central Oregon and northern Caliform'a, oc- 
cupies a vaUey in all essential respects similar to the valleys of the 
Great Basin lakes, and has at present no surface outlet, but as it has, 
within historic times, overflowed southward into Pit River, a tribu- 
tary of the Sacramento, it is considered part of the San Francisco 
Bay drainage basin. 

LAKES. 

About 1.13 per cent of the surface of Oregon is occupied by lakes, 
most of which are situated in the Great Basin region or in the Cas- 
cade Mountains. 



12 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

Tlio larger lakes, except Crater Lake, are situated in the central 
Oregon plateau region, and are subject to wide fluctuations in area. 
Many of them, such as the Warner Lakes and Goose Lake, are slowly 
diminishing as a result of deficient inflow; several, among them Mal- 
heur, Harney, Silver (Harney County), Goose, and the Warner Lakes, 
will eventually disappear, owing to the use of the tributary waters for 
irrigation. 

SWAMPS. 

The marshes that in places border Columbia and Willamette rivers 
are unimportant, but the long flat valleys of the Great Basin contain 
rich, fertile, swamp lands, susceptible of great development when 
drained. Much of Harney Valley may be classed as reclaimable 
swamp land, Blitzen Valley alone containing nearly 100,000 acres of 
marsh, most of which is now being drained. Chewaucan Marsh, below 
Paisley, contains more than 25,000 acres of land that has been drained 
and utilized for wild hay. Other important swamps are the Klamath 
marshes and the overflow lands of Warner Valley. Reclamation of 
these lands is either now under way or is contemplated. 

FLOODS. 

The rivers reach a high stage during winter, most often in January, 
and some rivers reach a second flood stage late in spring or early in 
summer. The winter flood is the normal result of increased precipi- 
tation in winter; the summer floods are caused by the melting of snow 
on the mountain slopes. Columbia River is exceptional in that its 
period of maximum discharge is in June, its winter discharge being 
relatively slight. The floods of the larger rivers are at times serious. 
A rise of more than 30 feet above low water has been recorded on the 
Willamette, and the Columbia sometimes reaches 60 feet above ex- 
treme low stage. 

COLUMBIA RIVER DRAINAGE BASIN. 

GENERAL FEATURES. 

Columbia River has its source in Columbia Lake, in the eastern divi- 
sion of the Kootenai district, in British Columbia, flows northwest 
to the fifty-second parallel of latitude, turns abruptly southward, 
nearly paralleling its former course, passes through a series of narrow 
lakes, and crosses the international boundary line near the northeast 
corner of the State of Washington, where it receives Clark Fork. 
After traversing Washington in a general southerly direction, it 
turns westward and forms the boundary lines between Washington 
and Oregon; it discharges into Pacific Ocean at the forty-sixth parallel 
of latitude. 



COLUMBIA RIVER DRAINAGE BASIN. 



13 



The total drainage area of the Columbia is estimated from the best 
available maps to be 259,000 square miles, divided as follows: 

Square miles. 

Oregon 55, 370 

Washington 48, 000 

Idaho 81, 380 

Montana 25, 000 

Nevada 5, 280 

Wyoming 5, 270 

British Columbia 38, 700 

This area is limited on the east by the Rocky Mountains and is 
traversed north and south by the Cascade and Coast ranges. Be- 
tween the mountain ranges are rolling, rough, and mountainous table- 
lands. Mean altitudes range from sea level near the mouth of the 
river, to 8,000 feet in the Rocky Mountains, 5,000 feet in the Cascade 
Range, and 1,000 to 4,000 feet in the intervening table-lands. Many 
peaks in the mountain ranges extend into the region of eternal snow 
the highest in the Cascade Range, including Mount Baker (10,827 
feet), Mount Rainier (14,408 feet). Mount Adams (12,307 feet). Mount 
Hood (11,225 feet), and Mount Jefferson (10,200 feet).

sional blockades from it-e, from Celilo to I^ewiston. It will be noted that part of Snake River, from mouth 
to Riparia, is now marked "navigable under favorable conditions." 



COLUMBIA RIVER DRAINAGE BASIN. 15 

The improvement of this river system for navigation is being car- 
ried on as rapidly as funds will permit. The work at present under 
way consists, briefly, of the deepening of the mouth of the Columbia 
River through the construction of jetties. In 1907 the Columbia 
bar had a navigable depth of approximately 26 feet at low tide; it 
is expected that when projects now under way are completed a depth 
of 40 feet may, if necessary, be obtained. The opening of the Cas- 
cade locks and canals to traffic in 1896 rendered the river navigable 
in one unit from the mouth to Big Eddy. With the completion in 
1915 of the locks and canal around the obstructions between Celilo 
and Big Eddy, a distance of about 8| miles, the Columbia is now 
open to steamboat navigation from Priest Rapids to the sea — a 
distance of 400 miles. 

The area drained by the Columbia includes perhaps the largest 
consolidated area of forests in the world. Originally almost the entire 
area, except those arid portions midway between the mountain 
ranges, was covered with dense forests, and although the territory has 
been settled for about sixty-five years and large areas have been cleared, 
the proportion of forested area to the entire area has been reduced 
but slightly. It is believed that at least 45 per cent (about 116,000 
square miles) of the drainage area of Columbia River is forested, 
and that about 58,000 square miles contain merchantable timber. 

The rainfall is distributed over the area most irregularly. From 
the Pacific coast eastward to the summit of the Coast Range the 
mean annual rainfall varies from 100 to 150 inches. In the basins 
between the Coast and Cascade ranges, it drops to about 40 inches per 
annum. It increases again to over 100 inches on the summit of 
the Cascade Range, and decreases very rapidly beyond the summit, 
until at the eastern base of the Cascades it has dropped to about 
14 inches. At the mouth of Snake River the mean annual rainfall 
is about 9 inches, but this extremely low rainfall obtains only in 
the lower altitudes. Beyond this point the rainfall again increases 
in Washington and northern Idaho to about 20 inches, whereas in 
eastern Oregon it continues at about 9 inches or less. In the eastern 
areas a large proportion of precipitation appears as snow, and durmg 
the winter months the streams are more or less icebound. West of 
the Cascade Range, however, the winter stream flow is not affected 
by ice. 

The climate of the area exhibits aU the variations from the rigor- 
ous climate of the northern latitudes, as found in British Columbia 
and the higher table-lands of Oregon and Idaho, to the mild climate 
of western Oregon and Washington. 

As regards irrigation, the area ranges from the extremely arid region, 
where irrigation is absolutely essential, through the semi-arid country, 
where dry farming and irrigation are practiced side by side, to the hu- 
mid country that^ strictly speaking, is arid in the summer months. 



16 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

In the Willamette Valley, for instance, where the mean annual 
rainfall is approximately 40 inches, only 5 per cent of this amount is 
received during the growing season, and the fullest agricultural de- 
velopment will not be realized until this entire portion of the area is 
brought under irrigation as completely as are the arid portions 
beyond the mountains. The irrigated areas of the Pacific Northwest 
are being extended so rapidly that it is almost impossible to keep pace 
with the development, and yet, comparatively speaking, a very 
small portion of the irrigable area has been developed. At present 
1,500,000 acres of land are under irrigation in the Northwest, and this 
area will be more than doubled when projects now being constructed 
are completed. Tlie values of irrigated agricultural lands vary from 
about $30 per acre for the poorest qualities of hay lands to $3,000 per 
acre for the intensely cultivated orchards. 

Columbia River and its tributaries afford at least one-third of the 
available water powers in the entire United States, but developments 
along this line have scarcely begun. About 250,000 horsepower are at 
present developed by water power in Oregon, Washington, and Idaho. 

Lumbering has been the principal industry of the Northwest, and 
the streams of the country have therefore been used not only for 
water-power development but for the transportation of logs from the 
timbered mountain slopes to the mills and factories in the valleys 
below. 'Comparatively few streams, however, carry sufficient water 
during the summer months, and it has been necessary to build tempo- 
rary dams on a large number of streams, where the logs are stored 
until released by opening the gates in the dam. The ''splash" thus 
caused usually suffices to carry the logs to their destination. 

The highest recorded flood in the Columbia River occurred in June, 
1894. The highest floods on the tributaries of this river are inva- 
riably caused by ''chinook" — a warm wind, usually accompanied by 
rain, occurring in the spring and fall. The fall ''chinook" usually 
brings the highest waters, since it may occur immediately after a 
heavy snow has covered the mountain ranges. The Columbia itself 
is not greatly affected at such times.

Bureau; read since February 1, 1892. Readings on other gages used are as 
follows: High- water periods, 1858 to 1877, gage of Oregon Steam Navigation Co. 
at Lower Cascades Landing; June 1 to December 6, 1878, gage of the United 
States Engineer Corps at Umatilla; December 12, 1878, to September 30, 1910, 
for periods when the Brooks gage was not read, gage of the United States 
Engineer Corps above the Cascades; October 10, 1879, to June 30, 1881, gage of 
the United States Engineer Corps at The Dalles. 

The Brooks gage has been washed out and replaced several times. It was 
probably checked occasionally by the United States Engineer Corps, but records 
of checking are not available. It was found to be correct in August, 1914. The 
United States Engineer Corps gage at The Dalles has been set at a number of 
arbitrary datums, all of which were carefully recorded ; for this report readings 
were all reduced to the datum of the Brooks gage. 

Channel. — ^Wide and deep; volcanic rock covered with sand and silt; control is rock 
reef at the Cascades; practically permanent. 

Discharge measurements. — Made as follows: In 1903, with floats and with current 
meter at Cayuse Rock, 7 miles below The Dalles; in 1907, with a current meter 
from a boat at The Dalles; in 1908, with floats at The Dalles; in 1910 and 1913, 
from the Northern Pacific Railway bridge just above the mouth of Snake River, 
the discharges of Snake, Umatilla, John Day, and Deschutes rivers at their 
mouths being determined from gage readings and added to the measured dis- 
charge to give the flow at The Dalles. In determining the mean gage height for 
these measurements an allowance of one day was made for the time interval 
between the mouth of Snake River and The Dalles. 

Rating curves. — Discharge estimates published in previous reports obtained by 
means of a rating curve based partly on two float measurements made in 1908, a 
coefficient of 1.05 having been used to reduce surface velocity to mean velocity. 
Later studies of vertical velocity curves of the Columbia indicate that a coefficient 
of 0.92 is more nearly correct. Rating curve adopted for revised computations 
passes through the two flood measurements made in 1913, close to the two float 
measurements made in 1908, as recomputed, and through the meter measurements 
made in 1907, 1910, and 1913. It averages the nine meter measurements made in 
1903 and is about 5 per cent larger than the average of the float measurements of 
that year. Measurements made 1903 not studied by the Geological Survey, but 
the meter measurements are considered the more accurate. Rating curves for the 
gages at Cascade Locks and Umatilla have been derived from The Dalles curve 
by comparison of gage-height records, monthly mean gage heights for two stations 
being plotted as coordinates and a relation curve similar to a rating curve being 
drawn. Comparative plots of monthly mean gage heights were made as follows: 
Cascade Locks with Umatilla, Cascade Locks with Celilo, Cascade Locks with 
The Dalles, and The Dalles with Umatilla. These comparisons indicate a change 
in the control for the gage at Cascade Locks which occurred approximately June 
1, 1884. The only available explanation of this change is contained in the an- 
nual report of Chief of Engineers, 1884, page 2246, referring to the Columbia 
at Cascade Locks. A large amount of blasting and excavating was done to im- 
prove the channel and obtain construction material, and this probably caused 
the change in control. Rating curve for flood gage heights at Lower Cascades 
Landing derived from that for Cascade Locks for 1879 to 1884 by means of a 
curve of relation for the same period. As high- water discharges of 1862 and 
1876 are checked quite closely by high-water marks at The Dalles and Cascade 
Locks, estimates of volume of floods in the earlier years are probably not mate- 
rially in error.

SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



Extreme stages. — The highest flood of which there is authentic record, that of June, 
1894, was caused by the coincidence of floods in upper Columbia River and in 
Snake River, accompanied by heavy rainfall in the lower drainage area. The 
snowfall all over the Columbia River drainage basin had been exceptionally heavy 
during the previous winter. The highest stage at Cascade Locks was 49.7 feet at 
4 p. m., June 6, corresponding to a discharge of 1,160,000 second-f^et, or 4.89 
second-feet per square mile. The flood of 1849 may have closely approached this 
flood in peak discharge, but there is no authentic record of flood stage for that 
year. The lowest stage of which there is authentic record occurred in January, 
1890, which also gives the lowest monthly mean on record. It was caused by a 
period of extremely cold weather following the driest year on record. The gage 
above the Cascades could not be read on account of ice from January 3 to 16, 1890. 
A reading was made on the gage below the locks January 7 and the discharge was 
determined from a relation of gage readings to be 41,900 second-feet. Any sudden 
drop in temperature when the river is low seems to cause a marked dropping off 
in discharge. It is probable that all the extreme low stages have been caused in 
this way. In the annual report of the Chief of Engineers, United States Army, for 
1879 it is stated that the low water of the previous winter, 0.5 foot on January 18, 
1879, which was the lowest for the preceding 10 years, was 2 to 3 feet higher than 
the low water of 1859 and 1862. This would seem to indicate that in the earliest 
years of settlement of the country there were periods during which the stage was 
as low as the lowest recorded stages, but probably no lower. 

Accuracy. — Results presented in this report considered fair for 1878 to 1884 and 
excellent for later periods. The area tributary to Columbia River between The 
Dalles and the Cascades is only about 1 per cent of the area above The Dalles, and 
the discharge from this intermediate area is not much more than 3 per cent of 
the total discharge. Variations in this intermediate inflow probably cause little 
inaccuracy in the results of studies of relations of gage heights. 

Cooperation. — Gage readings have been furnished by the United States Engineer 
Corps and by the United States Weather Bureau. Special acknowledgment is 
due to V. W. Tompkins, who has read the gage above the Cascades since 1891, 
and to S. L. Brooks, who read the Brooks gage from 1892 until quite recently. 
Mr. Brooks's earlier readings were made on his own initiative before he made 
any reports to the United States Weather Bureau. Discharge measurements of 
1903 were furnished by the United States Engineer Corps. The cost of the flood 
measurements of 1913 and of the recomputation of discharge has been paid by the 
United States Reclamation Service and from the appropriation made by the State 
of Oregon for the investigation of water-power jjossibilitics at The Dalles.

Note.— Channel below gage at Cascade Locks occasionally obstructed by ice which was noted by the 
observer, as follows: 1879, Dec. 23, large cakes of ice running; 1880, Dec. 4-14, river closed to navigation; 
1883, Feb. 4-26, river closed to navigation; 1884, river closed with ice Jan. 23 to Feb. 1 and Feb. 8-27, and 
gage frozen up Dec. 16-18 and 22; river closed with ice above locks Dec. 16, 1884, to Feb. 4, 1885, Jan. 17-29, 
1886, and Feb. 4-18, 1887; 1888, ice in river Jan. 6-29, and no boat ran to The Dalles until after Feb. 5; no 
boat to The Dalles Jan. 17-30, 1889, but no other notes of ice. Extremely cold weather began about Dec. 
12, 1889, and lasted until about Feb. 1, 1890, nearly 10 feet of snow falling during this period; river froze 
over Jan. 2, both gages were frozen up Jan. 4 and no regular readings made until Jan. 17. On Jan. 17 the 
gage below the locks was read, evidently by chopping away the ice. The river opened and a boat arrived 
from The Dalles Feb. 3; river frozen again Feb. 25; river blocked with floating Ice Dec. 21-23, 1892. Ice 
notes after 1892 are rather meager.

66 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

SNAKE RIVER BASIN. 
GENERAL FEATURES. 

Snake River, the largest tributary of the Columbia, rises among 
the high peaks of the Rocky Mountains in Yellowstone National 
Park, western Wyoming, and eastern Idaho, heading in the divide 
from which streams flow northward and eastward into the Missouri, 
southward to the Colorado and the lakes of the Great Basin, and 
westward to the Columbia. From Shoshone, Lewis, and Hart Lakes, 
in Yellowstone National Park, the river flows southward, broaden- 
ing into Jackson Lake (4 miles wide and 18 miles long) and passing 
through Jackson Valley (8 miles wide and 40 miles long), beyond 
which, near the Idaho-Wyoming line, it enters a long canyon. In 
the southern part of Fremont County, Idaho, it receives Henrys 
Fork, below which it flows southward and westward across Idaho to 
a point near Homedale, near the Oregon-Idaho line, where it turns 
abruptly northward and forms for about 170 miles the boundary 
between Idaho and Oregon, and for 30 miles more that between Idaho 
and Washington. At Lewis ton it crosses into Washington, flows 
northwest, west, and southwest, and joins the Columbia near Pasco. 

The principal tributaries of the Snake in Oregon are Owyhee, Mal- 
heur, Burnt, and Powder rivers. Pine Creek, Imnaha, and Grande 
Ronde rivers. 

OWYHEE RIVER DRAINAGE BASIN. 
GENERAL FEATITRES. 

Owyhee River rises in the Humboldt National Forest in the north- 
central part of Nevada, flows north, then northwest across the corner 
of Idaho and into Oregon, where it turns abruptly and flows north- 
eastward to its junction with Snake River, near Nyssa, Oreg., ex- 
actly opposite the mouth of Boise. River in Idaho. The total length 
of the river is about 220 miles, and the drainage area comprises 11,100 
square miles. 

The country drained is an exceedingly arid desert, the annual 
precipitation ranging from 6 to 9 inches, the larger part occurring as 
snowfall. Forests are entirely lacking except on the extreme head- 
waters, and even there they are small and the trees are those char- 
acteristic of arid sections. The general elevation of the river basin 
is about 4,000 feet, and the altitudes have but little effect on the 
precipitation. The streams are frequently frozen for a considerable 
period during the winter months, so that records for this part of the 
year are subject to inaccuracies. The low-water flow of this stream 
at the mouth is nearly aU taken by a large canal to irrigate lands 
lying between Owyhee and Malheur rivers. On the upper stretches 
of the river conditions are favorable for impounding the flood and 
winter flows for irrigation during the summer months, one large 
reservoir, the Duncan Ferry, having been surveyed by the United 
States Reclamation Service.

OWYHEE RIVER AT OWYHEE, OREG. 

Location. — In sec. 2, T. 21 S., R. 46 E., at highway bridge half a mile above Owyhee 
post office and 3 miles above mouth of stream. 

Records presented. — March 26, 1890, to December 31, 1893; January 1, 1895, to 
May 15, 1897; August 27, 1903, to September 30, 1910. 

Drainage area. — 11,100 square miles. 

Gage.— Chain gage used since July 28, 1904; inclined staff previous to that date. 
Datum of gage unchanged since 1903 but bears no determined relation to datum 
of gages used prior to 1897; all readings before 1903 refer to the same datum. 

Channel. — Sand and gravel; somewhat shifting; riffle control 200 yards below the 
gage shifts only during floods. 

Discharge measurements. — ^Made from the bridge or by wading. 

Winter flow. — Stream icebound for short periods; discharge relation at times some- 
what affected. 

Diversions. — Owyhee canal diverts water about 6 miles above station; practically 
the entire low-water flow is used for irrigation, and the discharge measured at 
the station at such times is mostly seepage water. Record was kept of the flow 
of the canal during 1903 to 1905. (See p. 86.) Considerable water also diverted 
for irrigation over entire basin. 

Accuracy. — Records as a whole are good, but those for 1891 to 1893, during which 
years no measurements were made, are subject to considerable uncertainty. 

Discharge measurements of Owyhee River at Owyhee, Oreg., in 1890, 1894-1897, 1903-1908.

Note.— Daily discharge determined as follows: 1880 to 1893. From rating curves well defined between 
200 and 12,000 second-feet for 1890, but somewhat uncertain for later years on account of lack of measure- 
ments. 1895 to 1897. Jan. 1, 1895 to Jan. 17, 1896, from cui^ve fairly well defined above 150 second-feet; 
Nov. 17-23, 1895, interpolated; Jan. 18, 1896, to May 15, 1897, from fairly well defined curve. 1903 and 1904. 
From curves well defined between 20 and 15,000 second-feet. 1905 to 1910. 1905, from well-defined curve; 
1906, from curve well defined between 500 and 15,000 second-feet and fairly wel 1 defined outside these limits 
for other years; discharge interpolated May 21 to June 5 and June 7-15, 1905, Dec. 29-31, 1907, and Aug. 28 
to Sept. 1, 1908, except May 27, 28, and June 12, 1905, on which dates discharge was increased by amount 
of water turned out of Owyhee canal. 

Estimated on account of ice Dec. 24-31, 1905; Dec. 17, 1908, to Jan. 6, 1909, and Dec. 12, 1909, to Feb. 25, 
1910; Dec. 12-31, 1909, estimated at 500 second-feet.

Wasteways. — There are five waste ways on the canal: The Fletcher (half a mile below 
the station), Cow Hollow, Locket Gulch, Emerson, and one near Ontario at the 
end of the ditch. The first two are above the river gaging station. 

Accuracy. — Results somewhat uncertain on account of weeds and the operation of 
wasteways and checks below the gage.

COLUMBIA EIVEE DRAINAGE BASIN. 89 

MALHEUR RIVER DRAINAGE BASIN. 
GENERAL FEATURES. 

Malheur River rises in the southeastern part of Grant County, flows 
southward to its junction with South Fork near Riverside and thence 
northeastward, receiving the North Fork near Juntura, Bully Creek 
at Vale, and Willow Creek about 4 miles below Vale, and discharges 
into Snake River at Ontario. Its drainage area, which includes the 
southeastern slope of the Blue Mountains and the eastern border of 
the divide that marks the boundary of the Great Basin in Oregon, is 
fan shaped, the outer border extending 140 miles along the mountain 
summits. The basin at the mouth of the river measures about 5,620 
square miles, and at Riverside below South Fork 1,910 square miles. 

Elevations within the basin range from 5,000 feet at the head- 
waters to 2,000 at the mouth. The country is in general rough and 
broken and is largely covered with sage brush. Irrigation is re- 
stricted to the lower lands immediately adjoining the streams. The 
headwater areas are lightly forested, but elsewhere the area is timber- 
less and is utilized as range land for cattle and sheep. 

The mean annual rainfall ranges from 16 inches on the headwaters 
to 10 inches at Vale. During the winter months the streams are 
icebound for part of the time. 

This area offers some exceptional advantages for irrigation, for 
large storage sites, and ample stream flow are conjoined with enormous 
areas of desert lands. The United States Reclamation Service has 
had under consideration at different times projects which con- 
templated the construction of reservoirs on the headwaters of the 
Malheur and its principal tributaries. 

During the period covered by these records, the flow of the Malheur 
appears to have been greatest in 1904 and lowest in 1895. The 
earher records are not so dependable as those of later years. 

MALHEUR RIVER ABOVE SOUTH FORK, AT RIVERSIDE, OREG. 

Location.— In the SW. I sec. 22, T. 23 S., R. 37 E., 200 feet above the mouth of 

South Fork, half a mile above Riverside post ofl3.ce. 
Records presented. — January 3, 1906, to March 31, 1907; December 15, 1908, to 

May 25, 1910. 
Drainage area. — 1,110 square miles. 
Gage. — ^Vertical staff gage 200 feet above cable since December 15, 1908. Temporary 

vertical staff 400 feet above cable January 3 to 23, 1906; inclined staff 15 feet 

below cable January 24 to March 29, 1906, when it was washed out. Temporary 

gage until May 8, 1906, when chain gage was installed. Location and datum not 

changed after January 24, 1906. 
Channel. — Gravel; somewhat shifting. 
Discharge measurements. — Made from cable. 
Winter flow. — Somewhat affected by ice. 

Diversions. — A large area of bottom land is irrigated with flood water above the station. 
Accuracy. — Results fair since 1908, but only approximate for 1906 and 1907 on account 

of lack of measurements and uncertainties in gage readings.

Note.— Daily discharge determined as follows: 1906 and 1907, from poorly defined rating curve; dis- 
• charge for January, 1907, estimated on account of ice; Jan. 1, 1908, to Mar. 2, 1910, from curve well denned 
between 60 and 800 second-feet; Mar. 3 to May 25, 1910, from fairly well defined curve; July 1-5, 1909, 
estimated from a hydrograph and Dec. 11-31 estimates reduced 10 per cent on account of ice. Estimates 
: for 1910 reduced 40 per cent Jan. 1 to 23 to counteract effect of ice; Jan. 24 to Feb. 13, 1910, estimated 
by comparison with records below the forks; Feb. 25 interpolated because of probable effect of ice jam. 
Daily discharge for Mar. 3-25 not published on account of the uncertainty of the gage heights. Dis- 
charge Apr. 19 to May 6 estimated from a hydrograph, as comparison with records for the station 
below the fork indicates that gage heights are doubtful. Discharge May 26 to 31 is the difference 
between the values determined for the station below the forks and for the South Fork.

a Estimated on account of ice. 

Note.— Monthly discharges for 1906-7 are only approximate. Discharge for March, 1910. estimated by 
comparison with near-by stations. Discharge for June to Sept., 1910, obtained by subtracting the dis- 
charge of South Fork of Malheur from the discharge below the mouth of South Fork. 



COLUMBIA RIVER DRAINAGE BASIN. 



95 



MALHEUR RIVER BELOW SOUTH FORK, AT RIVERSIDE, OREG. 

Location. — In sec. 22, T. 23 S., R. 37 E., about half a mile above Riverside post 

office, at the wagon bridge about 100 yards below the-mouth of South Fork. 
Records available. — ^January 16, 1909, to September 30, 1910. 
Drainage area. — 1,910 square miles. 
Gage. — Standard chain; prior to June 12, 1910, staff gages referred to slightly different 

datums. 
Discharge measurements. — Made from highway bridge or by wading. 
Channel. — Stones and small bowlders. Control may be changed by occasional ice 

jams. 
Winter flow. — River freezes over under bridge in cold weather; flow at riffle control 

apparently little affected. 
Diversions. — Some water is diverted for irrigating ranches along the river; probably 

only a small proportion of the total flow is used. 
Accuracy. — Results fair for ordinary stages; uncertain for extreme high and low 

water and for periods during which discharge relation is affected by ice.

Note.— Gage heights for 1909 are somewhat uncertain, as several gages, referred to slightly different 
datums, were used, and it is not always certain just which gage the observer used. .They have been cor- 
rected to uniform datum as closely as possible. Readings Jan. 17-23 and May 15-30 are believed to be 
erroneous. 
River probably frozen during a part of January and February, 1909 and 1910; effect somewhat uncertain.

Note.— DaHy discharge determined from a rating curve well defined between 50 and 1,500 second-feet. 
Mean discharge estimated because of ice as follows: In 1909, Dec. 12-31, 100 second-feet; 1910, Jan. 1-10. 
90 second-feet; Jan. 11-20, 200 second-feet; Jan. 21-31, 300 second-feet; Feb. 1-10, 100 second-feet; Feb. 16-24, 
500 second-feet. Discharge not computed for periods prior to Oct. 1, 1909, on account of uncertainty con- 
cerning gage heights and rating curve.

CANALS IN MALHETJB, RIVER BASIN. 



Systematic measurements of diversions from Malheur River were 
begun by the United States Reclamation Service in June, 1904, and 
continued until the end of the irrigating season of 1905. Sufficient 
measurements and readings on temporary gages were made to afford 
a basis for the estimate of total diversions given in the table on page 
149. Values for any one canal are liable to considerable error, but 
the total is believed to be fairly reliable. Considerable water was 
probably diverted in October and November, 1904, though no record 
was kept after September 30.

150 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

POWDER RIVER DRAINAGE BASIN. 

GENERAL FEATURES. 

Powder River, which drains the eastern slope of the Blue Moun- 
tains, rises in the extreme western part of Baker County, flows west, 
then north through Baker to the town of North Powder, where it 
turns abruptly to the southeast. It joins Snake River in the east 
central part of Baker County. 

The most important tributary stream is Eagle Creek, which drains 
the southern part of the Wallowa Mountains and enters the Powder 
near its mouth. The general elevation of the headwaters is 6,000 
feet above sea level; that of the valley is 3,300 feet. Sumpter is 
4,415 feet above sea level, and Baker 3,586 feet. The total drainage 
area of Powder River at the mouth is 1,660 square miles; at Baker 
it is 341 square miles. 

The headwater country is mountainous and heavily forested and the 
principal industry is mining and lumbering. The valley of the 
Powder has not been greatly developed, although a number of irri- 
gation ditches are in operation. Any extensive development will 
involve the construction of storage reservoirs, sites for which are not 
lacking. 

The mean annual rainfall at Baker is 13 inches; in the headwater 
region it is probably twice that amount, the greater part falling during 
the winter in the form of snow. The determination of stream flow in 
this area is rendered somewhat difficult during the winter as the 
streams are icebound for weeks at a time. 

The lowest run-off from this basin since records have been kept 
occurred in 1905; the highest occurred in 1904, but that of 1910 was 
nearly as high. 

POWDER RIVER AT SALISBTTRY,i GREG. 

Location. — In the SW. i sec. 30, T. 10 S., R. 39 E., at Salisbury station on Sumpter 

Valley Railroad, 10 miles above Baker. 
Records presented. — December 20, 1903, to September 30, 1910. 
Drainage area. — 230 square miles. 
Gage. — Vertical staff. Gage heights for 1910 refer to a datum 0.56 foot higher than 

that for previous years. 
Channel. — Gravel; somewhat shifting. 

Discharge measurements. — Made from wagon bridge or by wading. 
Winter flow. — River freezes deeply three or four months each winter. 
Diversions. — Most of low-water flow is diverted for irrigating small tracts along river 

above station. 
Accuracy. — Results fair. Marked diurnal fluctuation during spring, when snow is 

melting, decreases the accuracy. 

1 Referred to in earlier reports as near Baker City, Oreg.

Note.— The stage of the river fluctuates somewhat during the day on account of placer mining upstream; 
during the spring, when the snow is melting, there is a persistent diurnal fluctuation. Ice present during 
January, February, November, and December, 1905; Jan. 1 to Feb. 24, 1906; Nov. 19, 1906, to Feb. 10, 1907; 
Jan. 5-11 and Dec, 13-19, 1908; Jan. 1-16, 1909, and Dec, 10, 1909, to Mar. 1, 1910. Winter gage heights 
evidently read to water surface until about 1909, and to bottom of ice, or a little above the bottom, there- 
after. Gage heights after Jan, 1, 1910, refer to datum 0.56 foot above that used previously.

Note.— Daily discharge determined as follows: 
1904 to 1906. From rating curve fairly well defined below 800 second-feet, except for ice period, Jan. 1 to 
Feb. 24, 1906, and Nov. 19, 1906, to Feb. 12, 1907, for which curves were poorly defined. 

1907. From fairly well defined curves. 

1908. From poorly defined rating curve; estimated because of ice, Dec. 22, 1907, to Jan. 4, 1908. 

1909. From fairly well defined curve. Discharge for Jan. 1-16 and Dec. 10-31 obtained by open-channel 
curve reduced 20 per cent to counteract effect of ice, 

1910. From fairly well defined curve between 6 and 800 second-feet. 

Winter estimates of uncertain value, and for 1909 and 1910 they may be too small as observer was reading 
gage height to bottom of ice.

POWDER RIVER NEAR NORTH POWDER, OREG. 

Location.— In the NW. \ sec. 26, T. 6 S., R. 40 E., at proposed dam site for Thief 

Valley reservoir, 7 miles east of North Powder and about 8 miles southeast of 

Telocaset. 
Records presented.—March 9, 1909, to September 30, 1910 
Drainage area. — 826 square miles. 
Gage. — Inclined and vertical staff. 
Channel. — Bowlders and gravel; probably permanent. 
Discharge measurements. — Made from cable at gage section. 
Winter fiLow. — River freezes; discharge relation may be affected by ice two or three 

months. 
Artificial control. — A temporary dam, constructed each year about 1 mile above 

the station to subirrigate adjoining lands, may cause fluctuation in stage during 

low- water period . 
Diversions. — Most of low-water flow of Powder River and tributaries diverted above 

station for irrigation. 
Accuracy. — Results good. As a rule estimates of winter flow can not be made. 
Cooperation. — Gage readings furnished in part by Powder Land & Irrigation Co. 

Discharge measurements of Powder River near North Powder, Oreg., in 1909-1910.

Note. — Daily discharge determined as follows: 

1909. From well-defined rating curve; May 6-22, interpolated; Nov. 8-22, discharge obtained by open- 
channel curve reduced 20 per cent on account of ice. 

1910. From cur\'e well defined between 15 and 1,000 second-feet. 

Discharge for December, 1909, and January and February, 1910, can bo estimated approximately by 
taking twice the discharge at Salisbury and interpolating for the period Mar. 1-7.

166 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

GRANDE RONDE RIVER DRAINAGE BASIN. 
GENERAL FEATURES. 

Grande Ronde River, which drains the eastern slope of the Blue 
Mountains in Oregon and the northern slopes of the Wallowa Moun- 
tains (a comparatively high range that runs at right angles to the 
Blue Mountain Range), rises on the divide in the extreme southern 
part of Union County, flows in a generally northeasterly direction and 
unites with Snake River at Zindel, Wash., ah out 12 miles from the 
point at which the Snake crosses the Oregon- Washington line. 

The principal tributaries of the Grande Ronde are Joseph Creek, 
which drams the northern part of the Wallowa National Forest, the 
Wallowa, which rises in the southern slopes of the Wallowa Moun- 
tains, and Catherine Creek, which drains the western portion of the 
Wallowa Mountains. The drainage area of Grande Ronde River at 
its mouth is 3,950 square miles. Above the mouth of the Wallowa 
the drainage area is 1,590 square miles. 

The topography of this basin is in general rough, the area being 
almost entirely surrounded by moimtain ranges which slope grad- 
ually to Grande Ronde Valley, a large area of agricultural land 
approximately 2,700 feet above the sea level. The general elevation 
of the Wallowa and Blue mountains, from which the river receives 
its water supply, is 8,000 feet. 

The area drained by this river, except in the agricultural valleys, 
is almost entirely forested, a large part being included in the national 
forest reserves. The mean annual rainfall at La Grande is 19 inches, 
but on the headwaters of the stream it is probably 35 mches. The 
greater part of this precipitation occurs during the winter months as 
snow. The river is subject to an annual spring rise which is due to 
the melting of snow in the mountains, and damaging floods are 
frequently caused by the sudden melting of snows by chinooks. 

The agricultural activities have been confined largely to the pro- 
duction of wheat, and irrigation has not been practiced to an elabo- 
rate extent, although exceptionally good possibilities are afforded. 
Only the lower valley lands immediately contiguous to the streams 
have been irrigated, but there are at present under consideration a 
number of larger projects that involve the construction of reservoirs 
and the irrigation of large areas by means of long canals. Records of 
the flow of some of the streams in this basin have been kept since 1904. 
The year 1905 was a ''dry year" and all streams in the basin carried 
less water than during other years covered by the records. The 
year 1907 was a ''wet year."

GRANDE RONDE RIVER AT HILGARD, OREG. 

Location. — In sec. 32, T. 2 S., R. 37 E., about half a mile east of Hilgard, at the 

county highway bridge just below Five Points Creek, about 8 miles above head 

of Grande Ronde Valley. 
Records presented. — November 6, 1903, to March 3, 1910. 
Drainage area. — 660 square miles. 
Gage. — Vertical staff nailed to bridge abutment. 
Channel. — Sand and gravel; fairly permanent. The use of the stream for log driving 

formerly affected the discharge relation, especially for about two months in the 

summer. 
Discharge measurements. — ^Made from bridge or by wading. 
Winter flow. — Severely affected by ice one to two months. 
Artificial control. — Practically no diversions above station; some storage developed 

for flooding logs. 
Accuracy. — Results poor on account of logs and unfavorable conditions.

Note. — Daily discharge determined as follows: 

1903 and 1904. Nov. 5, 1903, to Apr. 12, 1904, from rating curve well defined between 40 and 1,000 second- 
feet; Apr. 13 to Dec. 31, 1904, from curve fairly well defined between 30 and 2,500 second-feet; Apr. 26, 
May 8 and 11, Oct. 2, 12, and 27, Nov. 5 and 18, 1904, interpolated, as stream was being used lor logging 
operations. 

1905. From rating curve well defined above 40 second-feet. 

1906 and 1907. From curve fairly well defined between 30 and 1,200 sccond-fcet. Estimated because of 
ice, as follows: Dec. 1-6, 1906; Jan. 7 to Feb. 4, 1907, 250 second-feet; Feb. 5-8, 1907, 840 second-feet. Dis- 
charge Mar. 8-11 and May 14 to June 30, 1906, estimated, on account of obstruction of stream by logs, from 
measurements. Discharge Mar. 14-22, 1907, also estimated because of log obstructions. 

1908. From poorly defined rating curve. 

1909. From poorly defined rating curve. Discharge obtained from open-channel rating curve Jan. 1-17 
reduced 25 per cent and Dec. 19-31 reduced 15 per cent to counteract elTect of ice. 

Estimates for days during the winter months other than those noted were probably affected by ice to a 
greater or less extent. 

Observer made no notes concerning logs at any time after May 1, 1907, so that no corrections have been 
applied and records aio accordingly subject to error.

Note.— Comparison of monthlj^ mean discharges of the Grande Ronde at Hilgard with those at the Elgin 
station below, where conditions are more favorable, indicates that the results obtained at the Hilgard 
station are as a whole fairly reliable, but that those lor the early part of 1908 may be too large. 



GRANDE RONDE RIVER AT ELGIN, OREG. 

Location. — In sec. 14, T. IN., R. 39 E., at the county bridge, one-fourth mile east 
of the nxilroad station, at the lower end of the Grande Ronde Valley. 

Records presented. — November 18, 1903, to September 30, 1910. 

Drainage area. — 1,350 square miles. 

Gage. — Standard chain; vertical staff at same datum used prior to July 21, 1904. 

Channel. — ^Heavy gravel and small bov/lders; fairly permanent. 

Discharge measurements. — Made from bridge or by wading. 

Winter flow. — Ice forms for a considerable period each winter, and has probably 
introduced some error into past records. 

Diversions, — Large part of low-water flow diverted above station for irrigation in 
Grande Ronde Valley. No storage developed. 

Accuracy. — Results fairly good.

WALLA WALLA RIVER DRAINAGE BASIN. 
GENERAL FEATURES. 

Walla WaUa River rises on the western slope of the Blue Moiintains 
and flows westward into the Columbia. Its drainage basin lies imme- 
diately north of that of the Umatilla and is in many respects similar. 

Altitudes within the basin range from 5,000 feet on the headwaters 
to 1,000 feet near Walla Walla. The mean annual rainfall ranges 
from 30 inches in the upper portion to 12 in the lower portion of the 
area. Only the upper part of the area is forested, and that in the 
manner characteristic of the Blue Mountains. The lower half is 
given to the production of wheat without irrigation, but the lands 
contiguous to the streams are extensively irrigated. 

Chmate and soil combine to make the country wonderfully pro- 
ductive, and the agricultural products range from the hardier forage 
crops to fancy fruits. 

The headwaters of the stream afford favorable opportunities for 
water power and storage which, if developed, would more than dou- 
ble the value of this stream. The entire low-water flow of the river 
is appropriated many times for irrigation, and the only solution to a 
situation that has been aggravated in the extreme and promises to 
become even more critical as additional areas are irrigated hes in 
the construction of storage reservoirs. 

The conditions for obtaining reliable records of stream flow are not 
good. The river throughout is swift, and the bed is composed of 
gravel that changes with every freshet. On this account the records 
are incomplete and usually cover the period between floods. Floods

ing great damage to life and property.

Channel. — Gravel; shifting. 

Discharge measurements. — Made at county bridge one-half mile below gage, 
except as noted . 

Diversions. — A ditch diverts water between the gage and the bridge from which 
measurements are made. The measured discharge of the ditch has been added 
to that of the river in the following list. 

Accuracy. — Conditions at this station poor and estimates generally uncertain, espe- 
cially after about July 1, 1904, when the discharge relation was affected by 
backwater from a diversion dam below the gage.

UMATILLA RIVEK BASIN. 



GENERAL J^EATUKES. 

Umatilla River rises in the northeastern corner of Umatilla County, 
Oreg., flows generally westward a distance of 80 miles, and unites 
with Columbia River at the town of Umatilla. The area above the 
town of Pendleton spreads out in fan shape, including the western 
slope of the Blue Mountains for a distance of about 70 miles. 

The principal tributaries are Birch, McKay, and Meacham creeks. 
The drainage area measures 2,160 square miles at the mouth of the 
river, 640 square miles at Pendleton, and 353 square miles at Gibbon. 



COLUMBIA RIVER DRAINAGE BASIN. 23l 

The mean annual rainfall ranges from about 30 inches on the 
summit of the Blue Mountains to 9 inches at the mouth of the stream, 
beins: 14 inches at Pendleton and 25 inches at Weston on the divide 
between Umatilla and Walla Walla rivers. The headwater regions 
of the stream are heavily forested, but downstream the forests give 
place to rolling table-lands devoted to the production of wheat. The 
immediate valley of the river has been irrigated for many years, and 
the entire low-water flow of the stream is appropriated for irrigation. 
The United States Keclamation Service has completed a project to 
irrigate about 20,000 acres near Hermiston, and has begun work on 
the West Extension, which will water about 30,000 acres along the 
Columbia River near Irrigon. The soil of this portion of the drainage 
basin is sandy and the climatic conditions are favorable for the pro- 
duction of fruit. The highest run-off since records have been kept 
occurred in 1900 and the lowest in 1905. 

UMATILLA RIVER AT GIBBON, OREG. 

Location.— In the NW. i sec. 36, T. 3 N., R, 35 E., on the Umatilla Indian Reserva- 
tion, 1 mile below Gibbon railroad station, about 1^ miles below the mouth of 
Meacham Creek, and 2 miles above the mouth of Squaw Creek; above all diver- 
sions. 

Records presented.— July 22, 1896, to December 31, 1899; April 15, 1900, to May 
29, 1906; December 3, 1906, to March 31, 1907; September 13, 1907, to September 
30, 1910. 

Drainage area. — 353 square miles. 

Gage. — Vertical staff in two sections; datum unchanged since December 3, 1906. 
Gages at several locations and datums used during life of station. 

Discharge measurements. — ^Made from a cable near the gage or, at low water, by 
wading. Several cables used. 

Channel. — Gravel; likely to shift at each flood. 

Winter flow. — Slightly affected by ice. 

Artificial control. — No water stored or diverted above station. 

Accuracy. — Results since October, 1904, good, except estimates of extreme high- 
water discharge, which are uncertain. Many of the records prior to May, 1904, are 
very uncertain on account of shifting conditions and lack of sufficient measure- 
ments.

UMATILLA EIVER AT PENDLETON, OREG. 

Location.— In sec. 10, T. 2 N., R. 32 E., at Main Street Bridge, in the town of Pen- 
dleton. 

Records presented.— February, 1891, to July, 1892; May 22, 1903, to March 21, 
1906. 

Drainage area. — 640 square miles. 

Gage. — Vertical staff fastened to center pier of bridge. 

Channel. — Gravel; shifts somewhat. 

Discharge measurements. — ^Made from different bridges in vicinity of station or, 
at low water, by wading. 

Diversions. — Byers Mill ditch diverts water about IJ miles above station and returns 
it to river about 200 feet above gage. Considerable fluctuation in the discharge 
is caused by unsteady operation of mill. The Farmers Mill ditch diverts water 
just above gage and returns it about 4,000 feet below; prior to June, 1904, it 
diverted about 40 second-feet; after that the quantity varied.^ 



For records of this ditch see p. 254. 



250 



SURFACE WATER SUPPLY OF OREGON, 18*78-1910. 



Accuracy.— Results for 1903 and 1904, fair; for 1905, good. Discharge for June to 
December, 1904, can not be computed, as most of the flow was diverted in the 
Farmers' Mill ditch, no record of which is available. 
Cooperation. — Records for 1891-92 furnished by Mr. A. L. Adams, cliief engineer 
of the Umatilla Irrigation Co.; accuracy of records not known. 
The following measurement was made by W. T. Trowbridge: 
January 24, 1894: Gage height on gage of Umatilla Irrigation Co., 1.53 feet; dis- 
charge, 239 second-feet.

Note. — Daily discharge determined as follows: 

1903. From fairly well defined rating curve. 

1904. From fairly well defined curve; Apr. 1-27, estimated as the sum of discharge of Umatilla River at 
Pendleton, McKay Creek, and Birch Creek, the discharge of which was estimated as one-half that of 
McKay Creek; Aug. 16 to Sept. 4, estimated at 42 second-feet. 

1905. From fairly well defined rating curve. 

1906. From curve well defined below 8,000 second-feet. 

1907 to 1909. From curve well defined between 100 and 8,000 second-feet. Discharge Mar. 16, 1908, esti- 
mateci from records at Umatilla. Discharge Jan. 10-16, 1909, determined from open-channel curve 
reduced 40 per cent; Jan. 17-19, interpolated on account of ice; Jan. 30 to Feb. 21, determined from 
corrected gage heights based on a relation curve between this station and that at Gibbon; approximate. 
(See footnote to gage heights.) 

1910. From two fairly well-defined rating curves applicable Jan. 1 to Mar. 2 and Mar. 3 to Sept. 30. Dis- 
charge determined from open-channel rating curves Jan. 3-10 reduced 10 per cent, and Jan. 11-17, 20 per 
cent to counterbalance effect of ice.

UMATILLA RIVER NEAR UMATILLA, OREG. 

Location. — In sec. 21, T. 5 N., R. 28 E., 1^ miles above Umatilla and mouth of river; 

near main line of Oregon-Washington Railroad & Navigation Co., one-fourth mile 

below diversion point of Oregon Land & Water Co.'s canal, and one-fourth mile 

above headgate of Brownell ditch. 
Records presented. — October 21, 1903, to September 30, 1910. Records show 

practically the total unappropriated flow of river except the amount diverted by 

the Oregon Land & Water Co.'s ditch. (See p. 276.) 
Drainage area. — 2,130 square miles. 
Gage. — Inclined staff in two sections; lower section 1.2 to 3.5 feet; upper, 3.5 to 

10.8 feet. 
Channel. — Solid rock without gravel or sand. One channel at all stages. 
Discharge measurements. — Made from cable or by wading. 
Winter flow. — Occasionally shore or floating ice; discharge relation not materially 

affected. 
Diversions. — Large part of total flow of river diverted for irrigation above station. 

The Umatilla project feed canal also diverts water during winter for storage in 

Cold Springs Reservoir. Low- water flow is mostly return water from lands under 

the Hermiston project and other irrigated tracts. 
Accuracy. — Results excellent.

WILLOW CREEK BASIN. 

GENERAL FEATURES. 

Willow Creek rises in the foothills of the Blue Mountains and flows 
northwestward into Columbia River near Arlington. Its drainage 
area throughout is practically timberless and is composed of high, 
rolling table-lands used for the production of wheat and as range for 
cattle and sheep. The creek is small but is subject to excessive and 
sudden floods. In 1903 this stream was the scene of the disaster at 
Heppner, where more than one hundred lives were lost from a sudden 
flood lasting scarcely more than an hour. The waters of the creek 
are used to some extent for irrigation in the immediate valley.

COLUMBIA EIVER DRAINAGE BASIN. 



287 



JOHN DAY RIVER BASIN. 



GENERAL FEATURES. 



John Day River drains the country to the northwest of the Blue 
Mountains. The river rises on the divide between Grant and Baker 
counties, Qreg., flows westward and then northward, and joins 
Columbia River about 28 miles above The Dalles, Its principal 
tributaries are North, Middle, and South forks. Its total drainage 
area is 7,800 square miles. 

The general elevation of its headwaters is about 6,000 feet above 
sea level; at Fossil the elevation is 1,500 feet. The headwater 
region of the stream is forested. Except wheat, which is grown on 
the rolling uplands by the ^'dry farming '^ process, no agricultural 
products of consequence can be raised without irrigation, and as 
only the immediate valleys of the streams can be readily irrigated, 
comparatively httle has been accompHshed. A number of projects 
are, however, contemplated, under which, by means of storage 
reservoirs and high-line canals, enormous areas of very productive 
table-lands would be utilized. The storage facilities are ample for 
this purpose. It is not likely that extensive development will be 
imdertaken until more detailed studies of flow have been made. 

The mean annual rainfall ranges from 24 inches on the headwaters 
to 10 inches at the mouth. The winters are cold, and the streams 
are frequently icebound throughout the greater part of the winter.

DESCHUTES RIVER BASIN. 
GENERAL FEATURES. 

Deschutes River has its source in a number of mountain lakes at 
the summit of the Cascades just over the mountains from the head- 
waters of Willamette River, and its course is northward to the Colum- 
bia, which it enters about 15 miles above The Dalles. 

The principal tributaries of Deschutes River are White, Warm- 
springs, Metolius, and Crooked rivers, and East Fork. All except 
Crooked River drain the eastern slope of the Cascades and contribute 
the larger portion of the stream flow. 

The drainage area of the river is largely indeterminate, as there are 
large areas along the topographical border of the basin which havQ 



COLUMBIA RIVEE DEAINAGE BASIN. 305 

no surface streams, the water all sinking into the soil and underlying 
rock and draining off underground. 

Topographically the area is rough and mountainous. The agri- 
cultural lands consist largely of high table-lands cut by deep canyons 
through which the rivers flow, and small arable areas which border 
the streams. The soil is a coarse disintegrated lava. The rocks of 
the entire area are volcanic and so peculiarly porous that the basin 
has the effect of a huge sponge. The flow of the Deschutes is more 
remarkably uniform than that of any river in the United States com- 
parable with it in size, and its economic value is almost incalculable. 
At the mouth of the stream the maximum flow is only six times the 
minimum. Ocular evidence of this uniformity of flow is presented 
by the low grass-grown banks between which the river flows for its 
entire course. 

The general elevation of the lands around Bend is 3,600 feet above 
sea level; that of the summit of the Cascade Mountains is from 5,000 
to 6,000 feet. Prineville is 2,868 feet above sea level, and Paulina, 
near the upper portion of the Crooked River basin, 3,684 feet. 

The only heavily timbered portion of this drainage basin is found 
on the eastern slope of the Cascades, and constitutes about 15 per cent 
of the total area. The divide between Crooked River and the John 
Day basin is sparsely timbered. The uniform flow of this stream can 
not be attributed to forestation. Indeed the entire timber supply 
could be removed without in the least affecting the flow of the river. 

The annual rainfaU ranges from 100 inches on the summit of the 
Cascade Mountains to 10 inches along the main course of the stream. 
Twenty-five miles farther east, at PrineviUe, the mean annual rain- 
fall is 9 inches; at Warm Springs, 11 inches; at Bend, 15 inches. On 
the headwaters of Crooked River the precipitation is probably 20 
inches or more. 

Although the winter temperatures are low, ice does not Usually 
affect the flow of the streams, for the winter flow is derived largely 
from springs. The high stages usually occur during the months of 
April, May, and June, and result from the melting of snows in the 
mountains, although occasionally floods are caused by ^^chinook" 
winds in the early spring or late fall. 

It has been estimated that Deschutes River between Benham FaUs 
and its mouth, a distance of 140 miles, together with its principal 
tributary, Metolius River, is capable of furnishing about 600,000 
horsepower from the low-water flow after all water possible has been 
diverted for irrigation. The United States Geological Survey has pub- 
lished a report on Deschutes River and its utilization,^ in which its water 
powers are described and the conditions of development discussed.

DESCHUTES RIVER AT WEST S RANCH, NEAR LAVA, OREG. 

Location.— At private bridge on B. F. West's ranch, in the SW. i sec. 31, T. 19 S., 
R. 11 E., about 2 miles north of Lava, about 16 miles above Bend, and about 7 
miles by river above Benham Falls, one-half mile below Spring Creek, and 2 
miles below East Fork. 

Records presented.— July 21, 1906, to February 20, 1909. 

Drainage area. — Indeterminate. 

Gage. — Vertical staff spiked to bridge approach; datum unchanged. 

Channel. — Sand and gravel; somewhat shifting; affected by weeds. Gradient of 
river is very flat — less than 2 feet per mile. 

Discharge measurements. — Made from private wagon bridge of logs and poles. 

Winter flow. — Unaffected by ice. 

Accuracy. — Results good. 

As this station gives practically the same discharge as the station at Benham Falls, 
the tables of monthly discharge of the two have been combined (p. 322).

Note. — Daily discharge determined as follows: 
1906. From well-defined rating curve. 
1907 to 1909. From curve well defined between 1,400 and 2,200 second-feet, except for short periods, which 

may be affected by backwater, as indicated by the erratic plotting of some measurements.

SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



DESCHUTES RIVER AT BENHAM FALLS, NEAR BEND, OREG. 

Location.— In the NE. I sec. 16, T. 19 S., R. 11 E., about 250 yards above Benham 
Falls, and 14 miles above Bend; above the more important irrigation diversions 
from Deschutes River, and just below the dam site of the proposed Benham Falls 
Reservoir, 

Records presented. — March 30, 1909, to September 30, 1910. Records at this sta- 
tion aro comparable with those at West's ranch, 17 miles upstream by river, 
July 21, 1906, to February 20, 1909. 

Drainage area. — Indeterminate. 

Gage. — Vertical staff driven into edge of stream on right bank. Maintenance of 
gage datum at times somewhat uncertain. 

Channel. — Sandy; may shift slightly. Considerable growth of weeds along the right 
bank. 

Discharge measurements. — Made from cable. 

Winter flow. — Not seriously affected by ice. 

Diversions. — The diversion of water by some small ditches that are taken out above 
this station has no appreciable effect on discharge. 

Accuracy. — Rating curve well defined. 

Cooperation. — Gage heights furnished by the Central Oregon Irrigation Co. 

As this record has been used as a basis for all studies of the possibilities of power and 
irrigation development on Deschutes River between West Fork and Crooked and 
MetoUus rivers, it has been extended by summing the discharges of the river at Bend 
and of diversions between Benham Falls and Bend for all periods from January 1, 
1905, to September 30, 1910, not covered by records at West's ranch. 

Discharge measurements of Deschutes River at Benham Falls, near Bend, Oreg., 1909-10.

DESCHUTES RIVER AT BEND, OREG. 

Location. — In tlie NE. I sec. 32, T. 17 S., R. 12 E., just below the power house of the 
Bend Electric Light & Power Co., at city pumping plant at Bend, 1 mile above 
the diversion dam of the North canal of the Central Oregon Irrigation Co. 

Records presented. — April 23, 1907, to September 30, 1910. 

Drainage area. — Indeterminate. 

Gage. — Vertical staff bolted to a bowlder. 

Channel. — Very rough and rocky, somewhat shifting. Logs lodged below cause a 
somewhat varying degree of backwater. 

Discharge measurements. — Made from Staat's bridge, three-fourths mile above 
pumping station and Bend dam; conditions unfavorable. 

Winter flow. — Unaffected by ice. 

Diversions. — The Pilot Butte and Central Oregon canals of the Central Oregon 
Irrigation Co. divert water 5 miles by river above the present gage and measuring 
section, and have been operated since 1905. No other important diversions. No 
storage yet developed. 

Accuracy. — Records covering the period January 1, 1909, to September 30, 1910, are 
good, and for certain parts of the period excellent. 

Cooperation. — Gage heights furnished by C. A. Stanburrough, engineer of the 
pumping plant.

COLUMBIA RIVER DRAINAGE BASIIT. 



331 



CENTRAL OREGON CANAL NEAR BEND, OREG. 

Location. — In sec. 7, T. 18 S., R. 12 E,, at a flume section ^ mile below the point 

where the waters in the main diversion canal are divided between this canal and 

the Pilot Butte canal; about 2 miles south of Bend. 
Records presented. — March 11, 1905, to September 30, 1910. 
Gage. — Vertical staff, consisting of a painted strip of galvanized iron nailed to the 

inside of flume on right side. 
Channel. — ^A plank flume of rectangular cross section provided with batting on 

bottom cracks. Flume rather unstable, but rating appears not to change. 
Discharge measurements. — ^Made from yoke of flume at gage section. 
Winter flow. — Canal operated almost continuously. The flow in winter is small. 

The fall through the section at the gage is sufficient to maintain open channel at 

all times. 
Accuracy. — Results good. 
Cooperation. — Gage-height record furnished by the Central Oregon Irrigation Co. 

Discharge measurements of Central Oregon canal near Bend, Oreg.,for 1905-1910.

shifting. 
Discharge measurements. — Made from a boat near the gage. 
Winter flow. — Not materially affected by ice. 
Diversions. — Flow affected by diversions as at Bend and Laidlaw stations. Apparent 

decrease in discharge between the two stations may be due to seepage of water 

into the river bed or to inaccuracies in the Laidlaw record.

DESCHUTES RIVER AT MOODY, NEAR BIGGS, OREG. 

Location. — In the SE. \ sec. 26, T. 2 N., R. 15 E., opposite Moody railroad station, 
1^ miles above the bridge of the Oregon- Washington Railroad & Navigation Co., 
about 5 miles southwest of Biggs, and 1^ miles above mouth of river. 

Records presented.— July 7, 1906, to September 30, 1910; records for 1908 and 1910 
somewhat fragmentary. 

Drainage area. — Indeterminate. 

Gage. — Staff in two sections — the lower inclined, the upper vertical. 

Discharge measurements.— Made from a cable about 450 feet above the gage. 



COLUMBIA KIVER DRAINAGE BASIN". 



355 



Diversions. — Summer discharge at this station has been progressively reduced since 
about 1904 or 1905 by diversions from the upper river. Some of this water returns, 
but the net reduction during midsummer is now probably 10 or 15 per cent. 

Accuracy. — Rating curve excellent, records good except for periods during which 
the gage-height record is fragmentary, and for which discharge has been estimated 
from studies of the records. 

Cooperation. — Gage heights furnished by M. A. Moody, The Dalles, Oreg. 

Discharge measurements of Deschutes River at Moody, near Biggs, Oreg., in 1906-1910.

Note. — Discharge for Mar. 1-14 and June to Oct., 1908, estimated by comparison with discharge at "West's 
ranch. 

Mean for Nov. 6-30, 1908, taken as mean for the month. 

Monthly means for April to September, 1910, were obtained from comparisons with the discharge of 
upper Deschutes River and its tributaries. The results obtained in different ways are so consistent that 
the values used can not be much in error.

250 second-feet. Monthly discharge included in table for Tumalo Creek above Wimer canal near Laidlaw. 



TUMALO CREEK NEAR BEND, OREG. 

Location. — In the SW . ^ sec. 23, T. 17 S., R. 11 E., at highway bridge on Bend-Sister 

road, 4 miles above mouth. 
Records available. — October 6, 1906, to December 31, 1908 (fragmentary). Station 

maintained in winter months only to insure a year-long record on the stream; 

upper station somewhat isolated and sometimes inaccessible in winter. 
Drainage area. — 57 square miles. 
Gage. — Vertical staff attached to abutment of bridge. 
Channel. — Rocks and gravel; somewhat shifting. 
Discharge measurements. — At ordinary stages made by wading; at flood stages 

made from the highway bridge. 
Winter flow. — Discharge relation considerably affected by ice during extremely 

cold weather. 
Diversions. — All the water of this stream diverted above station, making it dry during 

the irrigation season except for seepage return. 
Accuracy. — Results fair.

Records presented.— April 17, 1906, to September 30, 1910. 
Drainage area. — 63 square miles. 
Gage. — Vertical staff. 
Channel. — Gravel and rock; practically permanent; backwater from a changeable 

dam reaches gage and introduces changes in rating curve. 
Discharge measurements.— Made from a foot log just above gage or by wading. 
Winter flow. — Creek does not freeze over at station, but gage readings are occasionally 

affected by shore and anchor ice. Ice also tends to jam above dam and during 

extreme cold weather the effect is very marked. 
Diversions. — McAllister's ditch heads above this station and its flow is added to get 

the total. Low- water flow of stream is all diverted by several irrigation ditches 

below station. 
Accuracy. — Results good .

Note.— Conditions were changed early in November, 1906, by washing out of dam below; this was re- 
placed Nov. 28, and washed out again Dec. 3. Ice jam Dec. 1 and 13. 

The creek was frozen Jan. 10 to 24, Nov. 18, 27, and Dec. 14 to 19, 1907. 

Diversion dam of irrigating ditch began backing up water about May 3, 1907. 

The creek was frozen wholly or in part on the following dates in 1908: Jan. 31 to Feb. 7, Feb. 11 to 13, and 
21 to 23, Mar. 1 to 4, Oct. 21 and 22, Nov. 14, 15, and 26 to 30, Dec. 5 to 7, 10 to 12, and 14 to 31. Diversion 
dam for irrigating ditch was put in in the early part of April; it was washed out Apr. 19, and replaced 
during May and the first week in June. 

Ice affected the gage heights Jan. 1 to 13 and Nov. 10 to 31, 1909. No observations Jan. 13 to Apr. 17, 1909, 
because the gage v/as out of plumb, due to the ice jam in January. 

The rise in gage heights Jan. 2 to 13, 1910, and that of Feb. 22 were evidently due to shore and anchor ice.

COLUMBIA EIVER DRAINAGE BASIN. 



409 



CROOKED RIVER NEAR POST, OREG. 

Location. — In sec. 7, T. 17 S., R. 21 E., 12 miles above Post and half a mile below 

mouth of North Fork of Crooked River, at a point locally known as "Stewarts 

grade," just below dam site of proposed reservoir. 
Records presented. — November 9, 1909, to September 30, 1910. 
Drainage area. — Indeterminate. 
Gage. — Combination vertical staff and inclined staff. Vertical staff read at low water; 

datum lowered 1 foot October 22, 1909. All gage heights reduced to new datum. 
Channel. — Rocks and bowlders; probably permanent. 

Discharge measurements. — Made from cable at gage section. Conditions poor. 
Winter flow. — Stream freezes and water sometimes flows over ice; discharge relation 

affected for two or three months each winter. Estimates of discharge during such 

periods have generally been made by comparison with records of the Prineville 

station. 
Diversions. — A considerable and unknown quantity of water is diverted for irrigation 

above the station. 
Accuracy. — Results only fair on account of unfavorable conditions. 

Discharge measurements of Crooked River near Post, Oreg., in 1908-1910.

OCHOCO CREEK AND ELLIOTT DITCH AT ELLIOTT S RANCH, NEAR PRINE- 

VILLE, OREG. 

Location.— In the NE. I sec. 5, T. 15 S., R. 17 E., at Elliott's ranch, 6 miles east of 
Prineville, at the dam site of a reservoir proposed in connection with the develop- 
ment of the Ochoco project of the United States Reclamation Service. 

Records presented. — November 1, 1908, to April 30, 1910. 

Drainage area. — 300 square miles. 

Gage. — Vertical staff. No change in gage datum since July 15, 1909, when the gage 
was lowered 0.75 foot. All gage heights corrected to later datum. Gage on 
ElUott ditch is vertical staff 150 feet upstream from gage in creek. 

Channel. — Gravel. 

Discharge measurements. — Made from a cable near the gage and from foot plank 
over ditch. 

Winter flow. — Discharge relation not seriously affected by ice. 

Diversions. — Elliott's ditch diverts water from the left bank of the creek about 1,000 
feet above the gaging station. Records of the flow of the ditch are kept in order 
to determine the total flow past the gage. There are other diversions for irrigation 
farther up the creek. 

Accuracy. — Rating curve and records good .

HOOD RIVER BASIN. 



GENERAL FEATURES. 



Hood River is formed by the junction of East, Middle, and West 
forks, which drain the eastern and northern slopes of Mount Hood, 
and flows northeastward into Columbia River at Hood River. The 
stream is used for both water power and irrigation, and, being sup- 
plied from the glaciers on the mountain, the flow is well maintained 
through the summer months. 

The basin is heavily forested, though part of the area was burned 
many years ago. The mean annual precipitation at Hood River is 
36 inches. The valley of the stream is noted for its production of 
apples, berries, and other fruit. 



HOOD RIVER AT WINANS, OREG. 

Location. — In sec. 1, T. 1 N., R. 9 E., 300 feet below the junction of the East and 
West forks, half a mile from Winans, 4^ miles above Tucker's bridge, and 10^ 
miles above Hood River. 

Records available. — November 17, 1905, to March 16, 1907; January 16 to Septem- 
ber 30, 1910. 

Drainage area. — 252 square miles. 

Gage. — Staff in two sections on right bank; lower section inclined, upper vertical. 
Datum of gage prior to January 16, 1910, 0.50 foot lower than present. 



COLUMBIA RIVER DRAINAGE BASIN. 



425 



Channel. — Coarse gravel and bowlders; not likely to shift. 
Discharge measurements. — Made from cable near gage. 
Diversions. — Several canals divert water for irrigating small tracts above the station, 

and at least one diverts around the station. 
Storage. — A logging splash dam on West Fork was operated during 1906 and 1907, 

causing irregular rate of flow. 
Accuracy. — Results fair. 

Discharge measurements of Hood River at Winans, Oreg., in 1905, 1906, and 1910.

Note.— From March to June, 1906, there was more or less backwater, caused by debris. The flow is 
influenced by logging dams aV)Out 2 miles above the station. These gage heights represent only approxi- 
mately the daily means. 

Gage heights for 1910 refer to a datum 0.5 foot higher than that used in 1905 to 1907. No ice at this 
station.

SANDY RIVER BASIN. 
GENERAL FEATURES. 



Sandy River rises in the glaciers of Mount Hood and flows north- 
westward, uniting with Columbia River at Troutdale. It drains the 
western slope of the Cascade Mountains at their northern extremity 
in Oregon. 



COLUMBIA EIVER DRAINAGE BASIN. 



433 



The principal tributaries of the Sandy are Bull Run River, v/hich 
drains the Bull Run National Forest and furnishes the water supply 
for the city of Portland; Zigzag, Salmon, and Little Sandy rivers, 
and Camp and Still creeks. 

Elevations within the basin range from 647 feet above sea level at 
Bull Run post office to 11,225 feet at the summit of Mount Hood; 
Salmon post office is 1,000 feet, Bull Run Lake 3,161 feet, Govern- 
ment Camp 3,880 feet, and the summit of Zigzag Mountain 5,014 feet. 
The drainage area includes 247 square miles below the mouth of 
Salmon River. The drainage area of Bull Run River at the mouth 
is 168 square miles. 

The mean annual precipitation at Bull Run is 76 inches; at Gov- 
ernment Camp 87 inches. It is likely, however, that the figure 
for Government Camp is not representative because of the close 
proximity of the station to Mount Hood. A large part of the pre- 
cipitation on the headwaters falls as snow. In the foothiUs^ however, 
it nearly all appears as rain during the nine months from September 
to May. The value of the waters of this stream lies in their avail- 
ability for municipal water supplies and in the power that can be 
generated by them. Favorable sites for power development are 
numerous and the distance to an industrial center is not great. A 
large part of the basin is heavily forested, although there are many 
areas from which the timber was burned a good many years ago. 
These tracts have, however, grown up in second-growth timber and 
the underbrush is almost impenetrable.

BULL RUN RIVER NEAR BULL RUN, OREG. 

Location. — In eec. 25, T. 1 S., R. 5 E., 1^ miles above the intake of pipe line of 
Portland water supply, about half a mile below South Fork. 

Records available. — August 20, 1907, to September 30, 1910; also reading on a gage 
installed by the city water department January 5, 1895, to November 13, 1906. 

Drainage area. — 102 square miles. 



COLUMBIA KIVER DRAINAGE BASIN. 



445 



Gage. — Friez automatic since August 1, 1909; inclined staff about 1,000 feet above 
the screen house at the head works since 1907. The earlier readings were made on 
gages at the same location as the inclined staff and have been referred as nearly 
as possible to the same datum. 

Channel. — Gravel and bowlders at upper gage; shifts somewhat; large rocks at the 
lower gage, but the discharge relation during the low- water periods has been 
affected by backwater from a temporary brush and log diversion dam constructed 
each year and washed out by the first high water in the fall. 

Discharge measurements. — Made from cable at site of recording gage or by wading. 

Accuracy. — Results good since 1907. Earlier records uncertain on account of ques- 
tion as to permanency of channel and especially as to gage datum. Low- water 
results should not be given much weight, but the total yearly run-off is probably 
nearly as good as for later years. 

Cooperation. — Gage heights furnished by Portland water board; the entire record 
prior to August, 1907, worked up by the water engineer of the city.

Note.— Discharge Dec. 1, 1903, to Nov. 19, 1904, and Nov. 14, 1906, to Aug. 19, 1907, estimated from read- 
ings on gage No. 2, so called, in the concrete canal leading from the river to the screen house at the head- 
works. These readings bear a very uncertain relation to the discharge and the records are only roughly 
approximate. 

WILLAMETTE RIVER BASIN. 



GENERAL FEATURES. 

Willamette River drains a trough-shaped area, extending north and 
south between the Coast and Cascade ranges in Oregon. The area is 
roughly rectangular, approximately 140 miles long and about 85 miles 
wide. The Willamette proper is formed by the junction of three main 
tributaries which unite in the vicinity of Eugene; these are Middle 
Fork (considered the continuation of the main stream), Coast Fork, 
and the McKenzie. The river is navigable for ocean-going vessels 
from the mouth to Portland, and for ordinary river steamboats from 
Portland to Corvallis, except during a few months each year. From 
Corvallis to Eugene the river is navigable for light-draft boats during 
medium stages of the river. The falls of Willamette River at Oregon 
City are passed by a series of ^yq locks, which have just been pur- 
chased by the United States. 

The other principal tributaries of the Willamette are Santiam, Mol- 
lala, and Clackamas rivers. From the Coast Range flow Long Tom, 
Marys, Luckiamute, Yamhill, and Tualatin rivers. The drainage

From the summit of the mountain ranges the slopes are steep, but 
they merge gradually into a wide alluvial valley or gently rolling 
agricultural lands. 

The entire drainage area may still be considered densely forested. 
The portions of the basin that contribute to the flow of the streams are 
almost entirely within the boundaries of the national forests, and pri- 
vately owned timberlands extend from the boundaries of the national 
forests to the main stream in the valley, except where lands have 
been cleared. 

Although records of precipitation at the summit of the Coast Range 
are meager, it is likely that the total annual rainfall is as much as 150 
inches. On the eastern slope of the Coast Range precipitation de- 
creases very rapidly to about 40 inches, but it gradually increases 
again until at the summit of the Cascade Range it is approximately 
100 inches. From north to south the same general variation is 
observed, although the differences are not so striking. At the mouth 
of the river the precipitation is approximately 50 inches, in the vicinity 
of Corvallis about 40 inches, and at the summit of the Calapooya 
Mountains, which form the southern boundary of the drainage area, 
55 or 60 inches. Except on the summits of the mountain ranges this 
precipitation is almost entirely rain, 95 per cent falling during nine 
months, from September to May. On the mountain ranges part of 
the precipitation is snow, and the country is subject during the spring 
and fall to warm chinook winds accompanied by rather sudden melting 
of these snows, which frequently cause considerable damage from 
floods. During the growing season, when the precipitation rarely 
exceeds 2 inches, the country is practically arid. Although irrigation 
has not long been practiced in the valley, it is likely that before many 
years a large part of the agricultural bottom lands will be placed under 
irrigation. Small ditches and pumping plants have been constructed, 
and the returns from irrigated agricultural lands show an increase of 
from 50 to 500 per cent in production over the nonirrigated lands. 



468 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

Lying almost wholly within a narrow strip adjacent to the main 
divide of the Cascades, where the soil and underlying rock is porous, 
like that in the basin of Deschutes River, on the east side of the range, 
are a number of lakes and marshes which afford favorable sites for 
storage reservoirs. As a result the streams flowing through the lakes 
and marshes experience no pronounced floods and are characterized 
by a large low-water flow. The effect of reservoirs on the Willam- 
ette would not be so marked as on more flashy streams, but their 
operation would greatly enhance the value of the river for irrigation, 
power, and navigation. 

The highest known flood in the Willamette Valley occurred Decem- 
ber, 1861, when the discharge at Albany was 302,000 cubic feet per 
second. The highest gage reading at Portland since that date oc- 
curred in 1894, but was due to backwater from Columbia River. The 
years 1899 and 1907 were ^Vet years." The year 1905 was a com- 
paratively dry year. The longest record of stream flow in this basin 
has been obtained by applying recent measurements made at Albany 
to records obtained by the United States Weather Bureau since 1878. 

The results of profile studies in the Willamette basin have been pub- 
lished by the United States Geological Survey as Water-Supply 
Paper 349.

Note. — Daily discharge determined from a rating curve well defined between 2,700 and 13,600 second- 
feet and fairly well defined above. Measurements made in 1911 and 1912 indicate that the curve used 
gives results 5 to 10 per cent too large between gage heights 10 and 20 feet and somewhat too small above 
25 feet, but the effect on any yearly or monthly mean is slight. Discharge estimates for 1878 to 1880 are 
subject to much uncertainty, as the permanence of gage and channel since that time is questionable.

COLUMBIA EIVER DRAINAGE BASIN. 



535 



SANTIAM RIVER AT JEFFERSON, OREG. 

Location.— In the NE. I sec. 11, T. 10 S., R. 3 W., at the Southern Pacific Railroad 
bridge in Jefferson, about 2J miles below junction of North and South forks and 
about 9 miles above mouth. 

Records available. — October 8, 1905, to July 1, 1906; October 1, 1907, to September 
30, 1910. 

Drainage area. — 1,890 square miles. 

Gage. — Vertical staff on center pier of railrod bridge; some of the high- water readings 
have been made from a vertical staff on right bank. 

Channel. — Rock and coarse gravel; practically permanent. Readings in 1905 and 
1906 '^were affected by backwater from logs that lodged in the river below. 

Discharge measurements. — ^Made from Southern Pacific Railroad bridge or from 
the highway bridge just below it. 

Diversions. — The Albany power canal diverts water from South Fork of Santiam 
River near Lebanon; the Salem power canal, from North Fork of Santiam River 
near Stayton; and water is diverted from North Fork for irrigation near West 
Stayton. No measurements made of these diversions until 1911. The discharges 
presented herewith therefore represent unappropriated flow. 

Accuracy. — Results good for 1907 to 1910. Estimates of discharge withheld for 1905 
and 1906 on account of poor data. 

Cooperation. — Gage readings furnished by S. A. Pease, of Jefferson Mill Co., and the 
United States Weather Bureau. 

Discharge measurements of Santiam River at Jefferson, Oreg., in 1905-6 and 1908-1910.

Note. — Daily discharge computed as follows: Aug. 1 to Nov. 20, 1909, from rating curve for 15-foot weir 
allowance has been made for possible roundness of crest, velocity of approach, and leakage, approximate; 
Nov. 21-23, 1909, estimated by an engineer who was on ground at time; Nov. 24, 1909, to Jan. 15, 1910, 
from a rating cin-ve derived from the curve for weir and comparative readings on the lower and weir gages; 
poorly defined for January. 

Discharge over the 23-foot weir computed from a rating curve based on one discharge measurement and 
the weir formula, allowing for velocity of approach and assuming leakage of 10 second-feet through the 
weir; curve well defined below 100 second-feet and fairly well defined for higher stages.

Note. — Daily discharge determined from two rating curves, one applicable Nov. 1, 1905, to Jan. 31, 1907, 
well defined between 50 and 1,000 second-feet, and the other applicable Feb. 1, 1907, to July 12, 1909, well 
defined between 60 and 1,000 second-feet. Discharge Feb. 5-7, 1907, estimated. Discharge estimates 
below 160 second-feet, July to November, 1907, and July to September, 1908, obtained by comparison with 
records of Clackamas and North Fork of Santiam rivers, are subject to large errors and are given merely to 
show in a rough way the relatively low flow at low stages at this station compared with other streams 
rising in the Cascade Mountains.

SILETZ RIVER DRAINAGE BASIN. 

GENERAL FEATURES. 

Siletz River rises in the mountains in the? western part of Polk 
County, at an elevation of about 3,000 feet above sea level, flows 
in a general southwesterly 'direction to Siletz, in Lincoln County, 
and thence winds tortuously northward and westward until it enters 
the Pacific Ocean through Siletz River Bay, about 6 miles northwest 
of Kernville. Its total length is approximately 50 miles, and its 
drainage area measures about 320 square miles. 

Its basin is densely timbered throughout, although some areas of 
logged-off lands may be found on the lower reaches of the stream. 

The mean annual rainfall at the mouth of the river is 75 or 80 
inches; at the headwaters it is undoubtedly as high as 150 inches. 
The annual run-off shows about 9 second-feet per square mile of 
drainage area. The records thus far show very little variation in 
the total run-off of this drainage area, but it is probable that 1905 
would be classed as a dry year, and that 1910 may safely be considered 
a wet year.

SUEFACE WATER SUPPLY OF OREGON^ 1878-1010. 599 

UMPQUA RIVER DRAINAGE BASIN. 

GENERAL FEATURES. 

Umpqua River is formed by the junction of North Umpqua and 
South Umpqua near the city of Eoseburg in Douglas County, Oreg. 
The North Umpqua rises in Mardu Lake near the summit of the 
Cascade Range at an elevation of over 6,000 feet and pursues a 
westerly course. The South Umpqua is also formed by two forks — ■ 
the northern rising on old Bailey Mountain, about 4 miles south of 
Diamond Lake, and the southern on the northern slope of Abbot 
Butte, and the united waters flow westward and northward. From 
the junction of its principal forks, the Umpqua takes a tortuous but 
in general northerly course to Elkton, beyond which its course is 
more nearly westward until it debouches into the Pacific at Winchester 
Bay in the northwestern part of Douglas County. Its total drainage 
area comprises about 4,000 square miles. At Scottsburg, just above 
tide water, the area measures 3,070 square miles. The North Ump- 
qua drains 1,080 and the South Umpqua 1,990 square miles. The 
important tributaries of the Umpqua are Smiths River, which drains 
the low mountainous area near the coast; Elk Creek, draining the 
divide between the Umpqua and Willamette basins; and Cow Creek, 
which drains the divide between the Rogue River and Umpqua 
basins. 

The country is rough and mountainous, and the streams flow in 
comparatively narrow valleys bordered by narrow stretches of agri- 
cultural land. The general elevation of the headwaters is 6,000 feet, 
with a few snow-capped peaks 8,000 to 10,000 feet high. The ele- 
vation at Roseburg is 485 feet above sea level. The North Umpqua 
faUs over 3,600 feet in the 75 miles from Diamond Lake to Roseburg 
by the river channel. The lower portion of the Umpqua has com- 
paratively little fall, as is evidenced by the very winding character 
of the stream. 

The region is one of the most densely forested m the United States, 
and probably 80 per cent of the drainage area can be classed as 
heavily forested. About one-fourth of the forest area is included 
in the national forests; the rest is owned by corporations and indi- 
viduals. 

The mean annual rainfaU at Roseburg is 30 inches; at Drain, near 
the divide between the Willamette and Umpqua drainages, it is 48 
inches. At the mouth of the stream there probably is as much as 
60 inches per annum, while at the headwaters the precipitation is 
100 inches or more. Except on the headwaters all of this falls as 
rain during the nine months of the year from September to May.

SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



Little irrigation has been practiced in the Umpqua Valley, although 
a few small ditches may be found on the smaller creeks of the North 
and South forks. The agricultural products consist of grain and 
fruits. For the production of apples, prunes, and similar fruits, the 
climate and soil are especially well adapted. Although the possibili- 
ties for water-power development in this area are almost phenomenal, 
there are no important plants. 

There is a remarkable difference between the run-off of the North 
and South forks of the Umpqua which would have been very diffi- 
cult to detect except through actual records of stream flow. The 
annual run-off of the North Fork is 4 second-feet per square mile, 
whereas that of the South Fork is 1.6 second-feet per square mile. 
Since records have been kept highest run-off values were shown in 
1907. It is probable that 1905 was a year of low run-off, although 
the records do not cover that period. 

SOUTH UMPQUA RIVER NEAR BROCKWAY, OREG. 

Location. — In sec. 15, T. 28 S., R. 6 W., at Winston's bridge, 6 miles south of Rose-

east of Brockway, and 18 miles above the mouth of North Umpqua. 

Records presented. — December 6, 1905, to September 30, 1910. 

Drainage area. — 1,800 square miles. 

Gage. — Staff gage in two sections, the lower section inclined and the upper vertical. 

Channel. — One channel at all stages. Bed of stream at control, one-fourth mile below 
station, composed of bowlders; fairly permanent. Good measuring section. 

Discharge measurements. — Made from highway bridge at gage; prior to January, 
1907, made from cable 300 feet below the bridge. 

Accuracy. — Results good.

Note. — Daily discharge determined as follows: 

1905 to 1908. From rating curves well defined between 1,200 and 10,000 second-feet, and fairly well defined 
to 20,000 second-feet. Discharge estimated Nov. 3-18 and Dec. 17, 1905. Discharges in August, Septem- 
ber, and October, 1906, and July to October, 1907, probably somewhat large as water was below the zero 
of the gage and the observer reported the reading as zero. 

1009. From curve well defined between 1,100 and 10,000 second-feet. Discharge Aug. 8-31, Sept. 2-26, 
and Oct. 10-17, estimated from comparison of hydrographs for other stations in Umpqua River basin- 

1910. From curve well defined between 900 and 10,000 second-feet. Discharge July 8 to Sept. 2, estimated 
from comparison of hydrographs for discharge of North Umpqua River at Winchester. 
Measurements made in 1912 indicate that the high-water extension of the curves may be somewhat 

too large.

ROGUE RIVER DRAINAGE BASIN. 



GENERAL FEATURES. 

Rogue River drains the southwestern corner of the State of Oregon, 
its basin extending from the extreme western part of KLamath 
County across Jackson and Josephine counties, and including the 
northern half of Curry County. On its north are the Rogue River 
Mountains, on the east are the Cascades, and in the southern part 
of the area is a spur of the Siskiyou Mountains. In all the basin 
comprises 5,080 square miles. 

The river is formed by three principal forks — the North, Middle, 
and South — which rise among the peaks of the Cascade Range and 
imite near Prospect, in Jackson County. From this point the Rogue 
winds in a general westerly direction to the ocean, which it enters 
near the town of Gold Beach, in Curry County. In the lower half of 
its course the stream hugs closely the base of the Rogue River Range, 
and its principal tributaries are from the south, as is shown by the 
following table:

South Fork. 

Big Butte Creek (drainage area, 268 

square miles). 
Little Butte Creek (drainage area, 361 

square miles). 
Bear Creek (Stewart Creek) (drainage 

area, 380 square miles). 
Applegate River (drainage area, 606 

square miles). 
Illinois River. 

The North Fork, or main stream, derives its water from springs, 
possibly supplied from Crater Lake, which lies to the east in the 
center of Crater Lake National Park, at an elevation of 6,240 feet 
above sea level. This lake occupies the crater of an ancient volcanic 
mountain to which the name Mount Mazama has been applied. The 
lake has no visible outlet ^ nor any other reaching the surface within 
a few miles. The walls inclosing the lake are made up of alternating 
sheets of lava, dipping away from the lake practically in all directions, 
and are so porous as to afford an easy passage for much water. 
Springs are abundant and remarkable in size. Little and Big Butte 
creeks drafn the southern portion of the Cascade Forest Reserve. 
Bear Creek, formerly called Stewart Creek, drains the famous fruit 
section of Rogue River Valley; Applegate River drains the Siskiyou 
Mountains; and Illinois River the territory to the south of the main 
stream near the coast. 

The drainage area is in general mountainous, elevations ranging 
from sea level at Gold Beach to 9,760 feet at the summit of Mount 
McLoughlin (formerly known as Motmt Pitt) — a snow-capped peak 
dividing the drainage of Big Butte and Little Butte creeks. The gen- 
eral elevation of the mountain range at the headwaters of the Rogue 
is 6,000 feet. Prospect is 3,000 feet, Ashland is 1,938 feet, and Grants 
Pass 956 feet above sea level. 

The area is almost completely timbered, but the stand is not so 
heavy as on the area to the north drained by Umpqua River, as the 
precipitation is lighter. The mean annual rainfall at Gold Beach is 
86 inches, at Grants Pass 33, at Ashland 27, on the headwaters of 
Illinois River 70, and at Crater Lake 100 inches. At the headwaters 
of the stream the greater part of the precipitation is rain during the 
winter months.

SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



As is usual in regions where the precipitation is sufficient for the 
production of crops without irrigation, development along this line 
is inconsiderable. The ditch of the Rogue River Valley Canal Co., 
which diverts water from Little Butte Creek, is the largest in opera- 
tion. A number of little ditches are used to irrigate the narrow val- 
ley lands contiguous to the small streams. In this manner Ashland 
and Wagner creeks and Applegate River are largely appropriated for 
irrigation. It is realized, however, that the agricultural resources of 
this section of the country wiU not be utilized in the most economic 
maimer until irrigation is practiced extensively. The valley lands 
in the vicinity of Grants Pass along Bear Creek are particularly 
adapted to fruit culture, and the Rogue River VaUey has become 
justly famous for the excellent quality of apples, pears, and other 
fruits raised there. 

The streams of this area, like others draining the Cascade Range 
afford wonderful possibilities for water-povfer development. At 
present the only important plants are those of the California- 
Oregon Power Co. at Gold Ray and at Prospect. 

Stream measurements in this basin were begun in August, 1905. 
The highest run-off values are shown by the records for 1907. It 
is probable that the lowest values would have been found in 1905 if 
records for that year had been complete.

KLAMATH RIVER DRAINAGE BASIN. 

GENERAL FEATTJilES. 

Klamath River drains a territory lying east of the Cascade Range 
in south-central Oregon and south of the Siskiyou Mountains in Cali- 
fornia. The river rises in Upper Klamath Lake, flows generally 
southward, and reaches the Pacific Ocean at Requa on the coast of 
northern California. Only that part of the basin lying in Oregon 
has been studied in detail. The drainage from this portion of the 
area is collected in large lakes whose margins are wide shallow marsh 
lands covered with tules and aquatic plants. 

From Upper Klamath Lake, which stands 4,141 feet above sea 
level, flows Link River, a stream 1 J miles long, discharging into Lake 
Ewauna at an elevation of 4,080 feet. Klamath Falls, the principal 
city of this section, is located on Link River. From Lake Ewauna 
to the town of Keno, Klamath River flows through a flat, marshy 
country a distance of 20 miles. About 5 miles above Keno the river 
is connected with Lower Klamath Lake by a channel known as 
Klamath Straits. During high stages water flows from Klamath 
River into Lower Klamath Lake, and during low water the direction 
of the flow is reversed. About half a mile below Keno the river 
breaks over a rocky ledge, and here begins its precipitous fall of 100 
to 200 feet per mile to its mouth. 

The drainage area above Keno, exclusive of Lower Klamath Lake, 
is 3,150 square miles. The streams draining into Upper Klamath 
Lake head about 6,000 feet above sea level. The elevation of Kla- 
math Falls is 4,100 feet. 



656 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

The principal tributaries of Klamath Kiver are Williamson River, 
which drains the northern part of the Klamath Indian Reservation, 
Sprague River, which is tributary to Williamson River and drains 
the southwestern rim of the Great Basin divide in Oregon, and Anna 
River, which heads in a large spring supposed to be fed by the waters 
of Crater Lake. Lost River, although not a tributary of the Klamath, 
is usually considered with it, as the two are connected by a slough. 
Water formerly flowed either way, the direction depending on the 
heights of the streams, but the flow is now stopped by an artificial 
dike. 

The mean annual rainfall at Klamath Falls, about 12 inches, is 
fairly representative for this section of the drainage area. A large 
part of this precipitation occurs as snow. As nearly all the streams 
are spring fed and therefore rarely freeze, records of stream flow are 
little affected by ice. 

Irrigation is practiced extensively in the upper part of the area, 
although dry farming has been fairly successful. The agricultural 
products consist chiefly of forage crops, the country being well 
adapted to stock raising. Grains, alfalfa, and the hardier vegetables 
and fruits are grown with some success, but the climate is too rigorous 
for the intensive agriculture that is possible at lower altitudes. 

Within the period covered by stream-flow records the year of lowest 
run-off was 1905 and the highest 1907. 

Gage records have been obtained since 1904 on Upper Klamath 
Lake, Lower Klamath Lake, and Tule Lake, and during 1907 and 1908 
the three gages in Klamath River between Upper and Lower Klamath 
lakes were read. Since 1905 records of evaporation have been kept 
at Keno. 

WILLIAMSON RIVER NEAR KLAMATH AGENCY, OREG. 

Location. — In the NW. | sec. 7, T. 32 S., R. 9 E., at lower extremity of Klamath 
Marsh, at point locally known as Rocky Ford, 13 miles northeast of Klamath 
Agency. 

Records presented. — March 25, 1908, to June 26, 1910. 

Drainage area. — 1,160 square miles. 

Gage. — March 25 to October 17, 1908, vertical staff 1,000 feet above the cable. Octo- 
ber 17, 1908, Bristol self-recording gage was installed at same site; records obtained 
until December 31, 1908. May 30, 1909, gage moved to location of cable and set 
to read the same but at a different datum. New datum of gage, 4,622.19 feet 
above sea level. November 10, 1909, auxiliary staff gage installed below mouth 
of Spring Creek, about 11 miles below the station. Bristol self-recording gage used 
from April 15 to June 26, 1910. 

Channel. — Gravel and sand; considerable growth of aquatic plants. 

Discharge measurements. — Made from cable. 

Winter flow. — Somewhat affected by ice. 

Accuracy. — Estimates fair.

Note.— Daily discharge determined from two fairly well defined rating curves, one applicable for 1908, 
and tlie other for 1909 and 1910. Measurement made in 1910 probably not reliable. Discharge for January 
and February, 1910, reduced by varying amounts to allow for effect of ice, as indicated by the observer's 
notes. Discharge interpolated for days on which gage was not read

Note.— Monthly means for periods of infrequent gage heights obtained by interpolating between dis- 
charges for days on which the gage was read. 

UPPER KLAMATH LAKE NEAR KLAMATH FALLS, OREG. 

Location. — In sec. 30, T. 38 S., R. 9 E., at the outlet of Upper Klamath Lake, about 

2 miles northwest of Klamath Falls. 
Records presented. — ^May 28 to October 22, 1904; January 7, 1906, to September 30, 

1910. 
Gage. — Friez automatic register since February 16, 1906; vertical staff prior to that 

date. Zero of gage 4,136.13 feet above sea level. During 1904, vertical staff on 

Pelican Bay; zero 4,137.93 feet above sea level. 
Accuracy. — Gage heights are very much affected by the wind. The water is lowered 

as much as 6 inches near the outlet when the wind blows from the south and is 

raised as much above its normal level when the wind is in the opposite direction. 

There is a periodic oscillation when the wind blows for any length of time. 
Cooperation. — Station maintained by United States Reclamation Service since May, 

1909.

LINK RIVER AT KLAMATH FALLS, OREG. 

Location. — In sec. 32, T. 38 S., R. 9 E., at the county bridge over Link River at 
Klamath Falls, 1^ miles below outlet of Upper Klamath Lake, and immediately 
at head of Lake Ewauna. 

Records presented. — May 15, 1904, to September 30, 1910. 

Drainage area. — 3,110 square miles. 

Gage. — Chain gage at bridge. Since June 6, 1908, a Friez automatic gage has also 
been maintained in the rapids above the bridge. 

Channel. — Permanent at both gages; water swift at upper gage, sluggish at lower. 

Discharge measurements. — Made at the county bridge. 

Winter flow. — ^Gage height seldom if ever affected by ice. 

Diversions.^ — Since about September 1, 1908, water has been diverted around the 
Friez gage in the Keno canal on west side of river. This water, after being used 
in the Moore Bros, power plant, has been returned to the river between the Friez 
gage and the bridge. Measurements and records of the United States Reclamation 
Service have made possible a fairly accurate estimate of the amount of this diver- 
sion. It has been measured from time to time, but has been held fairly constant 
between dates of change. Some water has been wasted over a spillway just 
above the power flume, probably not more han 5 second-fe3t on the average. 
Water has also been diverted in the main canal of the Klamath project on the east 
side of the river, but only a small quantity prior to the irrigating season of 1911. 

Accuracy. — The records prior to June 6, 1908, especially the individual daily records, 
are not reliable. For longer periods — a month or more — the determination of 
mean flow can probably be accepted as not greatly in error. This condition is 
accounted for by the effect of wind on the discharge at this station. Until May 8, 
1908, the gage was situated at the bridge at the upper end of Lake Ewauna. At 
the outlet of Upper Klamath Lake the river breaks over a rather shallow ledge, 
A strong wind upstream blows the water back from this outlet and at the same

time increases the height of water on the gage by backing the water in Lake 
Ewauna, causing diminished flow with increased gage height. So great is this 
effect of the wind that the river has been known to go entirely dry for a few hours 
at a time. When the wind is downstream the flow of Link River is greatly 
inreased, but the surface of Lake Ewauna is so large that the increase in flow is 
not shown by the gage heights. In the long run these wind effects are no doubt 
compensating, but little dependence can be placed in the published daily records 
prior to March 7, 1907. On this date an anemometer was installed on the bridge 
and a ship's taffrail log was trailed in the water under the bridge. It was hoped 
that the daily reading from this log would afford some indication of the velocities 
with the anemometer records. Although the records obtained by this device 
were much more reliable during 1907 than previously, even they were not all 
that could be desired. It became evident that owing to the sudden changes of 
the wind complete data could not be obtained without automatic recording 
devices on both the log and anemometer. The method was effective, however, 
in reducing the probable error of the estimates from about 15 per cent to within 
less than 5 per cent. On June 6, 1908, a Friez gage was installed in the rapids, 
where it could be affected only by change in flow, measurements being made at 
the bridge as formerly. From that date until some time during the summer of 
1909 the records given by the Friez gage were reliable, but since that time, on 
account of diversions, damage resulting from logs striking the gage well, back- 
water from logs, and failure to keep the gage always at proper datum, the records 
are subject to some uncertainty; they are still, however, more reliable than 
records that can be obtained from gage heights at the bridge. 
Cooperation. — Since May, 1909, station has been maintained by the United States 
Reclamation Service, the Survey working up and publishing the data.

KLAMATH RIVER AT KENO, OREG. 

Location. — In sec. 31, T. 39 S., R. 8 E., at county bridge at Keno. 

Records presented. — May 31, 1904, to September 30, 1910. 

Drainage area. — 3,150 square miles (excluding Lower Klamath Lake drainage area). 

Gage. — Vertical staff nailed to bridge; datum unchanged. 

Channel. — Sand and clay; fairly permanent. Aquatic plants accumulate during 

low water. Immediately below station river breaks over a rocky ledge, falling 

about 200 feet to the mile. 
Discharge measurements. — Made from cable about 1,000 feet below gage. 
Winter flow. — River usually freezes over in winter, but as the water is deep and the 

ice never very thick the discharge relation is not seriously affected. 
Accuracy. — During low water the accuracy of the record is somewhat affected by 

the growth of weeds. Low-water measurements are also somewhat uncertain on 

account of the extremely low velocities. Wind also has an effect at times. No 

measurements made since 1909; later estimates somewhat uncertain. 
Cooperation. — Station maintained by the United States Reclamation Service since 

May, 1909.

KLAMATH EIVEB DRAINAGE BASIN. 



703 



LOST RIVER AT OLENE, OREG. 

Location. — In sec. 14, T. 39 S., R. 10 E., at highway bridge at Olene. 

Records presented.— May 24 to July 30, 1904; May 19, 1907, to September 30, 1910. 

Drainage area. — 1,290 square miles. 

Gage. — Vertical staff; also hook gage used since April 23, 1909. 

Channel. — A permanent rocky riffle 200 feet below the gage controls the gage heights. 

Discharge measurements. — Made from highway bridge except during extreme 

low water, when better measurements can be made by wading at the riffle. 
Winter flow. — Gage heights not seriously affected by ice. 
Diversions. — At a point 5 miles below this station a dam has been built to divert 

the water of Lost River through a canal into Klamath River and thus reclaim 

lands bordering on Tule Lake. 
Accuracy, — Conditions favorable for good results. 
Cooperation. — Station maintained by the United States Reclamation Service since 

May, 1909, but the records have been worked up by the United States Geological 

Survey.

Note.— Daily discharges determined as follows: From two fairly well defined rating curves applicable 
July 16, 1904, to May 17. 1906, and May 18 to Dec. 31, 1906; 1907, by indirect method for shiftiag channel. 
Discharge not computed after May 31, 1907, as records at Olene are almost directly comparable with those 
at Merrill and are much more reliable.

TTJLE LAKE NEAR MERE-ILL, OREG. 

Location. — In sec. 8, T. 41 S., R. 11 E., at J. F. Adams's ranch, near mouth of Lost 
River, 3 miles east of Merrill. 

Records presented.— May 17, 1904, to September 30, 1910. 

Gage.^ — Vertical staff fastened to post driven in lake bed. Datum of gage at present 
0.83 foot higher than when checked in October, 1904. This change was verified 
in June, 1907, and again in November, 1907. As graph of gage heights has failed 
to reveal any critical points that would account for a sudden change, it is likely 
that the gage was raised by the ice a little at a time during the winters of 1905-6 
and 1906-7. On account of this error the gage heights prior to May, 1907, should 
not be used for any refined studies. 

Cooperation. — Station maintained by the United States Reclamation Service since 
May, 1909; records prepared for publication by engineers of United States Geo- 
logical Survey.

MILLER CREEK NEAR LORELLA, OREG. 

Location. — In sec. 7, T. 40 S., R. 14 E., at the highway bridge 3 miles south of 

Lorella and 1 mile east of the Swingle ranch in Langell Valley, since April 1, 1909; 

August 10, 1904, to December, 1908, in sec. 12, T. 39 S., R. 13 E., 9 miles northeast 

of Lorella, at the lower end of Horsefly Valley. 
Records presented. — August 10, 1904, to September 30, 1910. 
Drainage area. — 270 square miles; at old station 220 square miles. 
Gage. — Friez automatic register. No change in datum since April 1, 1909. 
Channel. — Rocky and fairly permanent. 
Discharge measurements. — At medium and high stages made from highway 

bridge; low- water measurements made by wading at riffle. 
Diversions. — A small irrigating flume carrying about 1 second-foot diverts just above 

present station. 
Winter flow. — River freezes over completely; winter records not reliable. As the 

total annual flow, however, is the important feature, a large error during such 

periods is admissible without affecting the desired results. 
Accuracy. — Results fair; records somewhat fragmentary until Friez gage was installed 

January 30, 1910, but discharge has been estimated for all periods for which gage 

heights were missing. 
Cooperation. — Station maintained by United States Reclamation Service since 

May, 1909^ records worked up by engineers of United States Geological Survey.

Note.— Creek dry June 17 to Dec. 31, 1905, July 7 to Nov. 17, 1906, July 18 to Oct. 25, 1907, and July 1 to 
Nov. 10, 1908. During the winter stream freezes over at gage but not at the riffle control, so discharge 
relation is not materially affected by ice. Low gage heights Jan. 9-20, 1910, may be due to effect of low 
temperature on Bristol gage and not to low discharge.

GOOSE LAKE DRAINAGE BASIN. 



GENERAL FEATURES. 

Goose Lake is situated in the northern part of Modoc County, Cal., 
and southern part of Lake County, Oreg., about two-thirds of the lake 
being in Cahfornia, but by far the greater part of the valley being in 
Oregon. The lake lies 4,800 feet above sea level, is about 28 
miles long, 10 miles in maximum width, and not more than 20 feet in 
maximum depth. It is fed by 16 streams in California, draining an 
aggregate of about 250 square miles, and 6 streams in Oregon. It 
probably receives also a large supply of water from subsurface 
springs. The annual rainfall on the open surface of the lake has 
been estimated at 14 inches. 

It is said that in the early sixties an emigrant trail crossed the 
valley of the creek at a place where the water is now several feet 
deep, but a few years later the lake rose so as to extend several miles 
farther north than it now extends, and for a short time in 1869 it 
overflowed southward to the north fork of Pit River. In 1881 it is 
reported to have overflowed to Pit River for more than 2 hours 
during a severe storm from the north. Along the northern edge of 
the lake are considerable areas of marsh hay lands, but farther 
north the vaUey is an unreclaimed sagebrush desert except for a few 
homesteads. The lower end of the lake is bordered by lava beds 
through which some water may be lost by percolation. 

The water of Goose Lake is slightly alkaline, though considerably less 
so than that of other lakes in the vicinity. 

Drews Creek, Cottonwood Creek, and Thomas Creek, the principal 
streams flowing into the basin in Oregon, drain the southeast slope 
of a high timbered ridge near the southern corner of Lake County. 
The water of Drews Creek is utilized by the Goose Lake VaUey Irri- 
gation Co. for the reclamation of 40,000 acres of land in the Goose

SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



Lake Valley. A storage reservoir of 60,000 acre-feet capacity has 
been constructed on Drews Creek about 5 miles above the mouth of 
the river canyon. 

From this reservoir an irrigation ditch has been constructed which 
carries water along the borders of the valley both north and south 
of Drews Creek. A northern branch wastes into Thomas Creek near 
the city of Lakeview. There is also a good storage site on Cotton- 
wood Creek. The How of Cottonwood Creek is well maintained 
throughout the year, but Drews Creek is more flashy. 

COTTONWOOD CREEK NEAR LAKEVIEW, OREG. 
Location. — In sec. 29, T. 38 S., R. 19 E., at a dam site 10 miles northwest of Lakeview. 
Records presented.— November 22, 1908, to September 30, 1910. 
Drainage area. — 30 square miles. 
Gage. — Inclined staff; gage just above a weir at dam site used November 22, 1908, to 

January 18, 1909. 
Channel. — Clean gravel; fairly permanent; 10-foot weir November 22, 1908, to 

January 16, 1909; 15-foot weir January 17 and 18, 1909. 
Discharge measurements. — Made from a footbridge 40 feet below present gage; 

low-stage measurements made by wading near gage. 
Winter flow. — Gage heights at times affected by ice, but winter flow is so small that 

no serious errors are introduced into the estimates. 
Diversions. — ^None above station. 
Accuracy. — Conditions excellent and results fairly reliable except when large diurnal 

fluctuations are caused by melting snow during the early spring. 
Cooperation. — Station maintained in cooperation with Goose Lake Valley Irrigation 

Co., which furnishes gage-height record.

DREWS CREEK NEAR LAKEVIEW, OREG. 

Location. — In sec. 4, T. 40 S., R. 18 E., 1 mile below the Drews Creek dam, 13 miles 

southwest of Lakeview, 
Records presented. — ^January 16, 1909, to September 30, 1910. 
Drainage area. — 211 square miles. 
Gage. — Vertical staff at highway bridge installed March 1, 1910. Two gages had 

previously been used — inclined staff at station No. 1, at the dam site, January 16 

to May 31, 1909, and vertical staff at station No. 2, at a dump-car bridge 100 feet 

below the dam site, November 20, 1909, to February 28, 1910. 
Channel. — Gravel; not likely to shift; at highest stages stream overflows into a 

second channel. 
Discharge measurements. — Made from a wagon bridge near the gage or by wading. 
Winter j3.ow. — ^Winters are severe at this station, but the flow is so small that very 

little error is introduced in the estimates as a whole. 
Accuracy. — Records subject to considerable error on account of diurnal fluctuation. 

Present conditions favorable for good results; conditions at station No. 2 were 

very poor. 
Cooperation. — This station is maintained by the Goose Lake Valley Irrigation Co. 

(successor to the Oregon Valley Land Co.), which furnishes the records to the 

Survey.

Note.— Daily discharge computed by engineers of United States Geological Survey, chiefly from data 
furnished by the Lakeview Irrigation & Power Co. Discharge Jan. 1-15, 1909, estimated by comparison 
with records of Cottonwood Creek. Discharge Jan. 16 to May 31, 1909 (station No. 1), determined from 
rating curve v/ell defined between 100 and 900 second-feet. Discharge Nov. 20 to Dec. 3, 1909 (station No. 2), 
determined from a curve fairly well defined between 500 and 1,200 second-feet; uncertain below 500 second- 
feet; discharge Dec. 4, 1909, to Feb. 28, 1910 (station No. 2), obtained from a curve fairly well defined between 
70 and 1,500 second-feet; approximate below 50 second-feet. Discharge Mar. 1 to Sept. 30, 1910, determined 
from a rating curve well defined below 1.200 second-feet. Daily discharge for days on which gage was not 
read interpolated or roughly estimated from the record of discharge of Cottonwood Creek. No correction 
for effect of ice.

GREAT BASIN DRAINAGE IN OREGON. 



GENERAL FEATUIIES. 

In Oregon, as in other parts of the Great Easin, the surface waters 
collect in natural depressions in the ground. Where the flow into 
these depressions is sufficient perennial lakes are formed of such extent 
that evaporation balances the inflow; where the surface flow is insuffi- 
cient, intermittent lakes or playas are formed. The principal lakes 
in the Great Basin in Oregon are Warner, Abert, Summer, Silver, 
Malheur, and Harney. Except Silver Lake in Lake County and the 
three southerly of the Warner lakes, all these lakes are more or less 
alkaline. 



736 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

WARNER LAKE DRAINAGE BASIN. 
GENERAL FEATURES. 

Warner Lake includes a chain of lakes and marshes extending in 
a general north-south direction between two high escarpments in the 
southeastern part of Lake County. The waters of these lakes flow 
from south to north and the lakes in the southern end of the valley 
are therefore fresh whereas those at the northern end are alkaline. 
The larger lakes in the area, from north to south, are Crump Lake, 
Hart Lake, Flagstaff Lake, and Bluejoint Lake. The general eleva- 
tion of the water surface is about 4,460 feet. 

Protected by the high ridges that border it on both sides, Warner 
valley has reached a fairly high stage of agricultural development. 
At the base of the hills bordering the western shores of Hart and 
Crump lakes are a number of prosperous ranches whose products 
include fruit, grains, and nearly all agricultural crops. 

The principal streams in this basin are Twentymile Creek flowing 
from the south; Deep Creek, formerly caUed Warner Creek, flowing 
from the west; and Honey Creek, flowing from the west. These 
streams drain a high, practically timberless ridge, but the flow of the 
streams is well maintained during the summer months. Deep Creek 
is the most important of these streams and Honey Creek is the next, 
though Twentymile Creek furnishes about the same amount of water 
as Honey Creek. All three are used more or less for irrigation, and 
any additional development wiU require construction of storage res- 
ervoirs on their headwaters. 

Around the west side and north end of the valley is a large area of 
agricultural land which is now growing sagebrush. The Warner 
Lake Irrigation Co. has under contemplation the irrigation of these 
lands by water stored on the headwaters of Warner and Honey 
creeks. The project is to be developed under the provision of the 
Carey Act. 

TWENTYMILE CREEK NEAR WARNER LAKE, OREG. 

Location. — In sec. 24, T. 40 S., R. 23 E., about one-fourth mile above the bridge at 
the mouth of the canyon, about 2 miles south of Warner Lake post office. Below- 
all tributaries. 

Records presented. — March 1 to September 30, 1910. 

Drainage area. — About 169 square miles, including area tributary to Cowhead 
Lake, which overflows only occasionally. 

Gage. — Vertical staff in two sections about one-fourth mile above the bridge and 
above a fall in the stream. A gage at the bridge was read during March and April, 
but as the discharge relation was affected by backwater from a dam below, it 
was removed to the present site. So far as possible, however, all gage readings re- 
ferred to the present gage have been reduced to the same datum. 

Channel. — Bowlders and gravel; probably shifts slightly. 

JDischarge measurements. — Made from highway bridge or by wading. 



WAENER LAKE DRAINAGE BASIN. 



737 



Winter flow. — Creek freezes over at gage but practically always remains open at 

rock control below. 
Diversions. — Only a small amount of water diverted above the station. 
Artificial control. — Backwater from a diversion dam below the bridge may reach 

the gage, but did not in 1910. 
Accuracy. — Gage heights show marked diurnal fluctuations at times during the 

spring, thus causing considerable inaccuracy in the records. 
Cooperation. — Station maintained in cooperation with Warner Lake Irrigation Co.

Note. — Readings for March and April made at the bridge (lower) gage; those beginning in June at the 
upper gage. Readings on bridge gage after Apr. 19 discarded, as they indicate backwater from the diversion 
dam below. Probably no ice at this station during period covered by records. Readings for Mar. 1 and 2 
may have been made in the afternoon and are probably higher than the true daily mean.

Note. — Daily discharge determined as follows: Mar. 1 to 10, from a fairly well defined discharge rating 
curve; Mar. 11 to 23, by indirect method for shifting channels; Mar. 24 to Apr. 19, from a poorly defined 
curve; Apr. 20 to June 2, by means of a hydrograph drawn through the measurement of May 19 and fol- 
lowing the rise and fall of Deep Creek near Adel; June 3 to Sept. 15, from a curve well defined above 5 
second-feet; Sept. 16 to 30, from a rating curve well defined (by measurement of Sept. 30, 1910, and measure- 
ments in 1911) between 3 and 600 second-feet. 

Determinations for the early part of March, especially the first two days, are liable to considerable error, 
resulting from reading the gage but once daily during a time when there was considerable diurnal fluctu- 
ation.

Gage.— Vertical staff in two sections about 500 feet above the bridge and above a 
series of rapids; datum unchanged. A second gage installed at the bridge Feb- 
ruary 28, 1910, by the Warner Lake Irrigation Co. was at times affected by back- 
water from temporary dam below. 

Charmel.— Probably permanent; bed of stream composed of gravel and stone. 

Discliarge measurements. — Made from the wagon bridge or by wading. 

Diversions. — Several small ditches divert water for irrigation near the headwaters 
of the stream and five ditches take out within 6 or 8 miles above the station and 
carry water around it to irrigate several hundred acres of land; 2,000 or 3,000 
acres of land are watered by natural flooding near Big Valley and Crane Lake, 
but much of the water is probably returned to the stream. The combined 
capacity of the five ditches above mentioned is about 30 second-feet. Measure- 
ments of the combined discharge showed 25 second-feet of water in June, 1910; 20 
second-feet in April, 1911; 18 second-feet in July, 1911. Below the bridge the 
grade of the stream is very flat and water is diverted into the M. C. ditch by means 
of a temporary dam which is repaired at the beginning of each irrigation season. 

Winter flow. — Discharge relation may be slightly affected by ice during periods of 
extreme cold weather and occasionally by backwater from ice jams. Control 
usually remains open. 

Accuracy. — Determination of mean gage height is rendered rather difiicult during 
the spring by diurnal fluctuations, which, however, are not so marked as on 
Twenty-mile and Honey creeks. 

Cooperation. — Station maintained in cooperation with the Warner Lake Irrigation 
Co.

Note.— IcG probably existed Dec. 2 to 31, 1909. 

Discharge relation probably affected by ice Jan. 2-9, 1910. Ga^e carried out by flood and ice jam Jan. 23 
and replaced by observer Feb. 8. Creek somewhat obstrucU^d by ice Veh. 8 to 14, after which obstruction not 
probable. Gage heights Feb. 28 to Mar. 2 are the mean of several readings a day. The highest stage reached 
was 9.0 feet at 6 p. m. Mar. 2. Subsequent readings were made about noon each day, when the creek was 
at about its lowest stage in the diurnal cycle, and are therefore not fairly representative of the daily mean.

742 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

Daily discharge, in second-feet, of Deep Creek at Adel, Oreg.,for 1909-1910 — Continued. 




Note.— Daily discharge, except as noted, based on readings of the upper gage as published. Discharge 
May 11 to Nov. 20, 1909, determined from a rating curve fairly well defined above 50 second-feet; 
curve is based on one measurement in May and the form of the curve for the period following, but it gives 
results consistent with the daily discharge for low water of 1910. Discharge from Nov. 21, 1909, to Sept 30, 
19i0, determined from a ratuig curve well defined between 10 and 1,500 second-feet. 

Special methods used as follows: Jan. 2-9, discharge interpolated because of ice; Jan. 23, estimated, 
because of ice jam, at about one-half of open-channel discharge; Jan. 24 to Feb. 7 estimated, assuming that 
creek fell rather rapidly alter the high water; Feb. 8-13, estimate reduced on account of ice; Mar. 1-10, 
discharge taken from a hydrograph drawn by plotting as coordinates with time the discharge correspond- 
ing to gage readings on the upper gage and the measurements made by engineers of the Warner Lake Irri- 
gation Co.; probably represents the daily mean fairly well; Mar. 11-31, mean discharge determined from 
the two sets of gage readings on upper and bridge gage. 

The maximum discharge recorded, 4,950 second-feet, at 6 p. m. Mar. 2, 1910.

WAENER LAKE DEAINAGE BASIN. 



743 



HONEY CREEK NEAR PLUSH, OREG. 

Location.— In the SW. i sec. 20, T. 36 S., R. 24 E., half a mile above the mouth of 

the canyon, 1^ miles northwest of Plush, and 1 mile above the wagon bridge near 

Plush; below all tributaries. 
Records presented. — May 13, 1909, to September 30, 1910, 
Drainage area. — ^About 185 square miles. 
Gag-es. — The first gage was a vertical staff fastened to the wagon bridge, but as gage 

heights were affected by backwater from a temporary diversion dam below the 

station, a vertical staff in two sections was installed by the Warner Lake Irrigation 

Co., February 24, 1910, half a mile above the mouth of the canyon and 1 mile 

above the bridge. 
Channel. — Bed composed of gravel; shifts slightly. 
Discharge measurements. — ^At the original site made from the bridge; now made 

from cable near the gage or by wading. 
Winter flow. — Considerably affected by ice. 
Diversions. — Records at this point show the total run-off from the basin above the 

station except for a small amount of water diverted near the head of the stream 

and used to irrigate a few hundred acres. 
Accuracy. — Records fairly reliable, although some inacuracy is caused by diurnal 

fluctuations of the stream. 
Cooperation. — Station maintained in cooperation with the Warner Lake Irrigation 

Co.

Note.— Stream frozen over Dec. 7, 1909. Ice conditions probably existed throughout the month. All 
gage heights for 1909 refer to gage at bridge. Bridge gage read Jan. 1 to Apr. 16, 1910, gage in poor condition 
and flow affected by ice part of the time; gage height, can not be used except for period Jan. 18 to 23. 

Gage at the mouth of the canyon read from Feb. 24. Gage heights Feb. 24 to Mar. 5 taken from a hydro- 
graph plotted from both the direct readings on the upper gage and the readings on the lower gage reduced to 
corresponding heights on the upper by means of a curve of relation. Gage heights beginning Mar. 6 repre- 
sent one reading daily; no observations July 17 to Sept. 30. Gage heights for portions of November and 
December somewhat questionable. Probably no ice at the upper gage during the period of records.

Note. — Daily discharge Feb. 24 to July 31 determined from a fairly well-defined discharge rating curve. 

Daily discharge Feb. 24 to Mar. 5 — a period of great diurnal fluctuation— determined by applying the 
rating table to gage heights taken at 3-hour intervals from a hydrograph and using the mean of the 8 de- 
terminations of discharge as the discharge for the day. This method gives results considerably larger 
than those obtained by applying the rating table to the mean of the gage heights. 

Dally discharge for high-water period in January determined by assummg a discharge of 30 second- 
feet for the gage reading of Jan. 19 on the lower gage, and extending a curve through this point parallel 
to the curve derived from the relation of the gages in February and March; values Jan. 22 and 23 reduced 
arbitrarily for assumed effect of ice jam; discharge was further assumed to have fallen rather rapidly. 

Mean discharge for Feb. 1-23 estimated at 30 second-feet. 

Daily discharge July 17 to Sept. 30 estimated at 1.5 second-feet.

MISCELLANEOUS STATIONS IN WARNER VALLEY, 



A number of gaging stations were established by the Warner 
Lake Irrigation Co. in June, 1910, on Deep and Honey Creeks and 
their tributaries and records obtained for about six weeks. The 
records of the measurements and gage heights have been furnished 
by the company, but discharges have been computed by the United 
States Geological Survey.

ALBERT LAKE DRAINAGE BASIN". 



GENERAL FEATURES. 

Abert Lake is a strongly alkaline body of water lying near the cen- 
tral part of Lake County. It has a surface area of 60 square miles at 
an elevation of about 4,240 feet. The waters are largely supplied 
from Chewaucan River and Crooked Creek. 

Chewaucan River rises on the high divide in the southern part of 
Lake County and flows northward into Chewaucan marsh, through 
which it meanders in a southeasterly direction and flows into Abert 
Lake at its southern extremity. 

The principal agricultural development in the basin consists of the 
hay lands in the Chewaucan marsh and the area of irrigated lands 
bordering the marsh on the south and along Chewaucan River in the 
vicinity of Paisley. 



748 



SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



CHEWAUCAN RIVER AT PAISLEY, GREG. 

Location.— In the SE. ^ sec. 23, T. 33 S., R. 18 E., half a mile above the town of 
Paisley. 

Records presented. — ^January 4, 1905, to December 13, 1907; January 17, 1909, to 
September 30, 1910. 

Drainage area. — 272 square miles. 

Gage. — Vertical staff. 

Channel. — Probably permanent; bed composed of clean gravel; banks subject to 
overflow at stages above gage height 8 feet. 

Discharge measurements. — Made from cable-60 feet below gage or by wading. 

Winter j3.ow. — Affected by ice. 

Diversions. — The station is above all diversions except George Conn's irrigation 
ditch, which heads about 2 J miles above the gage on the left bank and diverts 
water around the station. Conn's mill ditch diverts water from the left bank 
about 250 feet below the gage, where a low timber dam has been constructed. 
The current is fairly swift between the gage and the dam and practically no back- 
water was noticeable prior to 1910. During 1910 there was probably a little back- 
water. The Brattain ditch diverts water about 300 feet below the gage on the 
right bank; it follows the foothills for many miles do^vn the river and supplies 
water for use in irrigating land immediately around Paisley and large areas of 
hay land in Chewaucan Marsh. 

Storage. — It has been proposed to store the water of Chewaucan River at a point 20 
miles upstream from Paisley to provide for the reclamation of a tract of 12,000 
acres northeast of Paisley under the terms of the Carey Act. The development 
of this project, however, has been hindered by water-right claims of the owners 
of hay lands in Chewaucan Marsh. These lands have been flooded during the 
spring and winter to a depth of several feet and, as all the water is claimed for 
this flooding, development work can not proceed until water rights have been 
adjudicated. 

Accuracy. — Estimates good. 

Discharge measurements of Chewaucan River at Paisley, Oreg., in 1905-6, 1909-10.

part of January, 1909, and Dec. 15, 1909, to Feb. 16, 1910. Discharge relation during 1910 may have been 
affected by the raising of a dam which diverts water into a mill canal about 250 feet below gage.

Note. — Daily discharge determined as follows: 

1905 and 1906. From two well defined rating curves; open-channel rating curves applied throughout both 
years; values for winter months subject to some error on account of ice. 

1907 and 1909. From curves well defined below 1,000 second-feet. Mean discharge estimated as follows: 
Apr. 1-9, 1907 700 .second-feet; Dec. 2-7, 1907, 26 second-feet; .Ian. 1-25, 1909, 60 second-feet; Dec. 15-31, 
1909, 90 second-feet. 

1910. From curve well defined between 35 and 1,000 second-feet. Mean discharge Jan. 1-19, estimated at 
70 second-feet. Effect of ice obstruction Jan. 20 to P'eb. 10, estimated from observer's notes; daily dis- 
charge for this period only approximate. Discharges interpolated for days on which gage was not read.

756 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

SUMMER LAKE DRAINAGE BASIN. 
GENERAL FEATURES. 

Summer Lake is a strongly alkaline body of water with a surface 
area of about 70 square miles, at an elevation of about 4,140 feet. 
The water is supplied largely from Ana River, a stream 7 miles long, 
which heads in five large springs on the northern border of the valley. 
These springs supply a continuous flow of about 145 second-feet. 
The water has a nearly constant temperature of 65°. 

The agricultural development in this basin is limited to a narrow 
strip lying at the foot of a high escarpment along the western shore 
of Summer Lake. This narrow strip is the most favored section in 
central Oregon and in it intensive agriculture has been practiced 
since 1848. The escarpment is effective protection against the cold 
winds from the west and north, which in passing over make an eddy 
drawing the warm air of the lake over the lands and serving to equalize 
the temperature. The region has long been famous for its fruit. 
Apples, pears, peaches, cherries, and berries of all kinds are grown in 
abundance and crop failures are practically unknown. 

Along the eastern shore of the lake and extending eastward into 
the wide valley adjoining Chewaucan marsh is a large area of agri- 
cultural land, a portion of which could undoubtedly be watered from 
Ana River and another portion from Chewaucan River. Projects 
looking to the irrigation of these lands have been under consideration.

Discharge measurements. — Made from foot log near the gage or from county bridge. 

Accuracy.— Discharge relation badly affected by backwater from the lake and tem- 
porary irrigation dams and gage heights are therefore not published. 

This stream is almost entirely fed by springs and its flow is practically constant.

SILVER LAKE DRAINAGE BASIN. 

GENERAL FEATURES. 

Silver Lake is a body of fresh water approximately 15 square miles 
in area, at an elevation of about 4,340 feet. The western, southern, 
and eastern borders of the lake consist of high escarpments; to the 
northwest is Paulina marsh. 

Silver Creek, Bridge Creek, and Bear Creek flow from Yamsay and 
Hagar mountains northward into Paulina marsh and thence south- 
eastward into Silver Lake. 

The water surface of the lake fluctuates considerably. During a 
succession of high-water years the water rises sufficiently to overflow 
into Thorn Lake and cover a small portion of the desert to the east. 
This fact perhaps accounts for the freshness of the lake. After a 
succession of dry years the lake surface diminishes and the waters 
become more and more alkaline until freshened again by another 
overflow. 

The lake dried up entirely in 1889 during an extremely dry time. 

The principal agricultural development at the present consists of 
hay lands in Paulina marsh and small irrigated tracts bordering the 
streams. During recent years all land suitable for agriculture has 
been taken as homesteads, and dry farming has been practiced with 
more or less success. 

To the northeast and practically connected with Summer Lake 
drainage basin is Christmas Lake Valley, a flat alluvial area com- 
prising 300,000 acres. This valley has no surface streams, but con- 
tains two or three small lakes. Alkali Flat, near the northeastern 



758 



SURFACE WATER SUPPLY OF OREGON, 1878-1910. 



part of the valley, is an intermittent lake; south of it Christmas Lake 
is a perennial body of water, at an elevation of 4,296 feet. North of 
Christmas Lake is Fossil Lake, and in the extreme southwestern por- 
tion and practically connected with Silver Lake basin is Thorn Lake. 
Nearly all the lands of Christmas Lake Valley have been taken as 
homesteads. Dry farming is practiced extensively and good crops of 
grain and potatoes and other crops have been raised. Water for 
domestic purposes is found in comparatively shallow wells. Near 
the eastern border of the valley, however, wells 40 feet deep have 
encountered salt water. 

SILVER CREEK NEAR SILVER LAKE, OREG. 

Location. — In sec. 28, T. 28 S., R. 14 E., 1| miles southwest of Silver Lake post office. 

Records presented.— November 24, 1904, to March 31, 1907; January 11, 1909, to 
September 30, 1910. 

Drainage area. — 221 square miles. 

Gage. — Inclined staff on the right bank. In April, 1910, the gage was found to have 
been raised from the true position and some of the gage readings for 1909 are 
therefore subject to error. 

Channel. — Fairly permanent; bed composed of rocks and gravel. 

Discharge measurements. — Made from a cable near the gage or by wading. 

Storage. — ^As the normal summer flow of nearly all the streams in this region is appro- 
priated for present irrigation requirements, any additional development will 
require storage. Several fairly good sites are available on Silver Creek above 
areas of agricultural land that could easily be irrigated from stored waters. 

Accuracy. — Conditions favorable for good results. Records probably reliable.

Note.— Daily discharge determined from rating curves applicable as follows: 1905, fairly well defined; 
1906, well defined above 50 second-feet; 1907 to 1910, fairly well defined. Open-chaimel rating curve applied 
throughout the years 1905 and 1903; values for the winter months probably somewhat too large. The 
following estimates and corrections have been made: Jan. 1-16, 1909, discharge estimated 30 second-feet; 
gage heights Dec. 16, 1909, to Feb. 1, 1910, reduced 0.2 foot before applying rating curve, to allow for ob- 
struction of channel by ice. Discharge Feb. 2-8 interpolated on account of ice jam.

condition last half of December, 1905. Creek frozen Jan. 1 to about Mar. 20, 1906, the ice reachini; a thick- 
ness of 1.1 feet; backwater from irrigation diversion darn after Apr. 19, 1906. Backwater from irrigati on 
dam Apr. 17 to July 17, 1909. Creek frozen Jan. 1 to Mar. 1, 1910, and during part of December preced- 
ing; Feo. 6, 1910, ice about 20 inches thick; relation of gage height to discharge probably little affected by 
ice after the thaw at the end of February. 

The rise Apr. 16 was caused by backwater from a temporary brush dam which is placed each year to 
divert water into canals. The dam was not removed until after records were suspended July 6. No 
records July 6 to Sept. 24. The maximum stage was 10.0 feet at 8 p. m. Feb. 24.

Note.— Daily discharge for periods of unobstructed channel determination from a cur^^e fairly well 
defined between 4 and .50 second-feet, but uncertain above on account of the lack of high-water measure- 
ments during winter floods. 

Due allowance has been made for backwater caused by a temporary dam below the gage for the follow- 
ing periods: Apr. 18 to July 20, 1905; Apr. 19 to June 30, 190G; Apr. 17 to July 18, 1909; Apr. 16 to July 6, 
1910. The correction curve is defined by the rise in stage when the dam is put m, the fall when it is re- 
moved, and by one or two measurements each year. 

Corrections have been made for ice during the following periods, using the best data available: Nov. 8-13, 
Dec. 16-31, 19a5; Jan. 1 to Mar. 20, 1906; Dec. 19-31, 1909; Jan. 1 to Feb. 24 and Dec. 19-31, 1910. 

Discharge estimated July 20-31, 1906, Jan. 1-11, 1909, and July 7-31, 1910.

MALHEUR AND HARNEY LAKES DRAINAGE BASIN. 



GENERAL FEATURES. 

Malheur and Harney lakes, which are in Harney County, occupy a 
large basin lying in general 4,100 feet above sea level and rimmed by 
mountain ranges whose elevation is between 5,000 and 7,000 feet. 
They are connected by a small strait known as The Narrows, through 
which the water of Malheur flows into Harney Lake. For this reason 
the water of Malheur Lake is practically fresh, whereas that of Harney 



774 SURFACE WATER SUPPLY OF OREGON, 1878-1910. 

Lake is alkaline. The average rainfall in the basin is about 10 inches ; 
on the summit of the divide it is probably 18 inches or more. 

The agricultural lands in this basin comprise nearW 700,000 acres 
of flat alluvial soil forming a circular valley surrounding the lakes and 
extending like fingers into the vallej^s of tributary streams. 

The lower lands are more or less swampy and have for years been 
utilized as hay flats. During the spring months, when water is 
abundant, small rock-and-brush dams sufficiently high to cause the 
streams to overflow their banks are constructed at convenient points. 
Much of the meadow lands may thus be covered by a foot or more of 
running water during five or six weeks of the season. As the stream 
flow diminishes the swamp and hay lands gradually drain until the 
middle of July, when they are sufflciently dry to permit the cutting 
of hay. 

Comparatively small areas are cultivated, and on these the crops 
are limited to rye, oats, and barley. The principal industry of the 
region has been stock raising, and this has afforded a ready market 
for all grain and hay that could be raised. During recent years, 
however, much of the hay lands have been taken as homesteads and 
the better lands are rapidly being developed. 

The principal streams in this basin are Donner und Blitzen River, 
from the south, and Silvies River from the north, flowing into Mal- 
heur Lake ; and Silver Creek, flowing from the northwest into Harney 
Lake. South of Silver Creek, in a flat valley, lies Silver Lake, a small 
play a which is supplied by overflow from Silver Creek. Donner und 
Blitzen River, with its principal tributaries, Keiger, McCoy, and Mud 
creeks, drain the western slope of S teens Mountain. This mountain, 
which is the most prominent topographic feature in the area, is a long 
timberless ridge extending northeast and southwest, with a crest 
length of 60 miles or more. The eastern slope forms an abrupt 
escarpment; the western slope, which forms a gradual ascent, is 
deeply cut by canyons, into which great quantities of snow are drifted 
each year, the most notable being the gorge of Keiger Creek. The 
snows melt gradually, and the flow of the streams draining the western 
slope of the mountain is maintained well into the summer. The flow 
in late fall and winter is maintained from springs. 

vSilvies River drains the northern part of the Malheur-Harney 
basin, rising in the heart of the Blue Mountains, flowing generally 
southward through a broken country to Harney Valley, which it 
traverses in a southeasterly direction, and emptying into swamp 
lands bordering the northern shores of Malheur Lake. A large part 
of its drainage area is heavily timbered. The stream is flashy, being 
subject to severe floods. The summer flow is small and comes 
mostly from Emigrant Creek, a tributary from the west. " 



MALHEUR AND HARNEY LAKES DRAINAGE BASIN. 



775 



Silver Creek heads in a spur of the Blue Mountams and flows 
southeastward through Silver Creek VaUey into Harney basin. 
The upper part of its drainage area is well timbered, but the lower 
part is bare, The stream is subject to sudden floods and in summer 
its flow practically ceases. 

Between Silvies River and Silver Creek and flowing in the same 
general direction is Sagehen Creek, a small stream heading in a 
spur of the Blue Mountains and draining a rough, broken country. 
It empties into the marsh surrounding the northern end of Malheur 
Lake near the point where Silvies River enters this marsh. 

The eastern rim of Harney Valley is broken by a low pass known 
as Malheur Gap. Through this gap a drainage canal could be exca- 
vated that at the deepest part would not require a cut of more than 
18 or 20 feet. This canal would carry the waters of the lakes into 
Malheur River by way of a tributary of the South Fork. Such a 
project was at one time begun, but riparian owners of the lake 
border feared that the absence of these large bodies of water would 
have an unwholesome effect on the climate of the basin. Accord- 
ingly an injunction was issued restraining the company from bufld- 
ing the project. 

MALHEUR LAKE AT NARROWS, OREG. 

Location. — In sec. 26, T. 26 S., R. 31 E,, at the highway bridge across the channel 
connecting Malheur and Harney lakes, a few hundred feet north of Narrows. 

Records presented.— May 14, 1903, to July 21, 1906, and September 4-8, 1909. 

Gage. — ^Vertical staff on highway bridge. The datum of this gage was 8.20 feet when 
installed in 1903, referred to a bench mark at the east end of the bridge, elevation

Note.— Gage height 1.40 represents surface of dry bed. From about Sept. 1, 1903, water at gage was 
disconnected from Malheur Lake and subsequent records do not agree with fall of lake surface until some 
time in 1904.

SILVIES RIVER NEAR SILVIES, OREG. 



Location. — In sec. 14, T. 20 S., R. 31 E., at the site of a proposed dam about 3 miles 
southwest of Silvies, Oreg., three-fourths mile below Trout Creek, and 1^ miles 
west of the Burns-Canyon City road. 

Records presented. — May 9, 1903, to December 31, 1904; January 1, 1909, to 
September 30, 1910. 

Drainage area. — 510 square miles. 

Gage. — An inclined staff on left bank, 50 feet below cable. 

Channel. — Shifts somewhat at flood stages; bed composed of clean gravel; banks 
covered with heavy brush. 

Discharge measurements. — Made from cable or by wading. 

Winter flow. — Affected by ice. 

Storage. — A dam constructed at the site of the station will impound all the run-off 
from the drainage basin above it, and the water so stored could be diverted from 
this stream to irrigate lands in Harney Valley. The project was at one time under 
investigation by the United States Reclamation Service, but has since been 
taken up by the Silver Valley Irrigation Co. 

Accuracy. — Conditions fairly favorable for accurate determinations of discharge. 
The relation between gage height and discharge is materially affected by ice 
during the winter, but allowance for this factor has been made in the estimates.

Note.— Daily discharge dstermined from three fairly well defined ralinf,' curves, applicable 1903, 1904, 
and 1909-10; discharge Jan. 1-14, 1909, estimated because of ice; discharge Jan. 15 to Feb. 16, 1909, derived 
from open-channel curve, compared with discharge at Burns station, where there was little ice, and reduced 
40 per cent. Mean discharge Jan. 1 to Feb. 25, 1910, estimated at 30 second-feet; discharge determined 
from open-channel curve Feb. 20-28 reduced, as ice was still in bottom of river. No correction for ice 
Mar. 1-4; values may be somewhat too high, as ice was present.

SILVIES RIVER NEAR BURNS, OREG. 

Location. — In sec. 7, T. 22 S., R. 30 E., 10 feet below a wagon bridge near Parker's 
house, 10 miles north of Burns. 

Records presented.— May 10, 1903, to July 24, 1906; December 14, 1908, to Sep- 
tember 30, 1910. 

Drainage area. — 940 square miles. 

Gages. — An inclined and vertical staff. 

Channel. — May shift slightly; bed composed of gravel; stream flows through a flat 
slluvial bottom between banks covered with a dense growth of willows and 
underbrush. Above a gage height of 13 feet the stream overflows a wide area. 



784 



SURFACE WATER SUPPLY OF OREGON, 1878-1010. 



Discharge measurements. — ]\Iacle from a cable at Lampshire 's ranch, 1 mile above 
the gage. 

Winter flow. — Effect of ice small. 

Utilization. — The water of Silvies River is largely used for the flood irrigation of 
hay lands in Harney A'alley. As even the flood discharge is so used, any irriga- 
tion project that would require the diversion of the water would involve the set- 
tlement of accrued water rights. 

Accuracy.— Conditions unfavorable for accurate determination of discharge. 

Discharge measurements of Silvies River near Bums, Oreg. in 1903-1906, 1908-1910.

o Estimated. 

Note.— Monthly discharge computed by adding the estimated diversion of the canal to the discharge 
determined from observation at the lower station. Discharge for January, 1909. and August and Septem- 
ber, 1910, estimated by comparison with records derived from observations at other stations and by assum- 
ing that the low-water discharge in 1911 was fairly representative of that in previous years. Figures 
originally published for the lower station for July to September, 1909, have been discarded as probably too 
high, for the channel was obstructed during that period. 

The figures for each month are liable to considerable error, but they afford a basis for an approximat^e 
estimate of the total yearly discharge.

DONNER UND BLITZEN RIVER NEAR DIAMOND, OREG. 

Location. — In sec. 8, T. 32 S., R. 32| E., at wagon bridge near "P" ranch buildings, 
about 23 miles southwest of Diamond. 

Records available. — January 27, 1909, to July 31, 1910. 

Drainage area. — 200 square miles. 

Gage. — Vertical staff just below bridge. 

Channel. — Gravel and sand; practically permanent; banks covered with under- 
brush and subject to overflow. 

Discharge measurements. — ^Made from bridge or by wading. 

Winter flow. — ^Affected by ice. 

Diversions. — Five ditches divert water above the station and about 300 feet below a 
brush and rock dam diverts water into a sixth ditch. No record has been kept of 
the actual time of operation of these ditches. 

Accuracy. — Owing to changes in the diversion dams and lack of accurate information 
of diversions, estimates can only be considered fair. 

Cooperation. — Maintained in cooperation with the William Hanley Co. 

Discharge measurements of Donner und Blitzen River near Diamond, Oreg., in 1909-10.

Note.— Gage heights from about Jan. 24 to Eeb. 7, 1910, increased by effect of a driftwood jam on a riffle 
below. A dam about a mile below the gage, used to divert water into a canal, was raised prior to the 
measurement on May 21, probably some time in March or April. 

Relation of gage height to discharge probably not affected by ice.

Note.— Daily discharge determined as follows: Feb. 1. 1909, to Mar. 20, 1910, from fairly well defined 
rating curves; Mar. 21 to July 30, 1910, from poorly defined curve. From July to September, 1909, and per- 
haps for a longer period, gage heights were affected by a dam below the gage; the stability of this dam and 
its exact period of operation are uncertain. Mean discharge Nov. 21-27, 1909, estimated at 200 second-feet. 
Discharge estimates arbitrarily reduced Jan. 24 to Feb. 7, 1910, to allow for effect of wood jam.

Note.— Daily discharge determined from a rating curve fairly well defined between 10 and 120 second-feet, 
but verj"- vmcertain above. Determination for the winter period somewhat imcertain, as ice affected, to 
a slight degree, the relation of gage height to discharge.

MALHEUR AISTD HAEITEY LAKES DEAIXAGE BASIX. 



801 



SILVER CREEK NEAR RILEY, OREG. 



Location,— In sec. 30, T. 22 S., R. 26 E., 12 miles above Riley, 3 miles below the 
junction with Nichols Creek. 

Records available. — April 14, 1904, to July 14, 1906; February 15 to December 12, 
1909; April 6 to September 30, 1910. 

Drainage area. — 260 square miles. 

Gages. — Vertical and inclined staff. At the point where this station has been 
located Silver Creek is divided into three channels by an earth and rock dam. 
The original gage, established in 1904, was placed in the third or left channel. 
Wlien the station was reestablished in 1909 a new gage was installed on the right 
bank. 

Channel. — Clean gravel; not likely to shift. 

Discharge measurements. — At the original station measurements were made from 
the three bridges which cross the channels. After the station was reestablished in 
1909 measurements were made from a cable Vv^hich was installed 50 feet below the 
new gage, 300 feet above the bridges, and about 100 feet above the dam. The 
dam is rather unstable, as the brush, earth, and smaller stones are washed away by 
the first flood and are not replaced until the water subsides in the spring. The 
1909 gage heights were affected by these changes. 

Winter flow. — Relation of gage height to discharge affected by ice. 

Diversions and storage. — The water of Silver Creek is used to irrigate hay lands 
in the upper Silver Creek Valley. Below this point the valley narrows to a canyon 
and opens out again near Silver Lake into lower Silver Valley. During the years 
of low run-off no water from the upper valley reaches the lower. The Silver 
Creek reservoir site, which was investigated by the United States Reclamation 
Service and also by the Silver Valley Irrigation Co., is 3 or 4 miles above the gaging 
section. Water stored at this point could be used to irrigate large areas of agri- 
cultural lands on both sides of the stream. 

Accuracy. — Results at this station are only approximate. 



Discharge measurements of Silver Creeh near Riley, Oreg., in 1903-1910.

Note.— Creek frozen Nov. 14-20 and Dec. 4-11, 1909. Creek dry Aug. 3 until about Oct. 1, 1910. Dis- 
charge relation somewhat affected by backwater from a dam below; observer notes changes in dam Apr. 
23 and May 20, 1910, which no doubt caused the increase in stage on those days. 

Daily discharge, in second-feet, of Silver Creek near Riley, Oreg., for 1904-1906, 1909-10.

Note.— Daily discharge determined from rating curves applicable as follows: 1904, fairly well defined; 
Jan. 1, 1905, to Mar. 31, 1906, well defined; Apr. 1 to July 14, 1906, fairly well defined; 1909, poorly defined; 
determinations for individual days or weeks in 1909 are liable to fairly large errors, but the mean for the 
whole period may not be much in error; 1910, fairly well defined. Mean discharge estimated as follows: 
Feb. 1-14, 1909, 25 second-feet; Apr. 1-5, 1910, 200 second-feet. Discharge estimate derived from open- 
channel curve Dec. 13-31, 1909, reduced on account of ice.
